Reactions of Carbonyl Compounds with Benzyl Chloromethyl Ether of Diiodomethane in the Presence of Samarium(II) Iodide or Metallic Samarium. New Routes to 1,2-Diols, Iodohydrins and Cyclopropanols

Carbonyl compounds react with benzyl chloromethyl ether in the presence of samarium(II) iodide to afford the corresponding addition products which, when subsequently hydrogenolysed, yield 1,2-diols.Simple aldehydes and ketones react with diiodomethane in the presence of samarium metal to give iodohydrins in good yields.Under similar reaction conditions, alpha-halogeno substituted ketones and aromatic 1,4-diketones are converted into cyclopropanols.These cyclopropanations have been shown to rpoceed through the initial generation of samarium enolates, followed by the Simmons-Smith type reaction.A novel transformation of esters to cyclopropanols via tandem one-carbon homologation is also described.

Quinolinyl-Thienyl Chalcones as Monoamine Oxidase Inhibitors and their in Silico Modeling Studies

Mitochondrial enzymes, monoamine oxidases (MAO) are thought to be emerging and useful therapeutic target for neurodegenerative disorders. Monoamine oxidases have two isoforms, A and B. MAO-A is related to metabolism of amine neurotransmitters in the brain whereas MAO-B is concerned with aging related neurodegenerative disorders. Therefore, the identification, characterization and discovery of new and potent MAO-A and B inhibitors is crucial in advancing neurodegenerative therapeutic research. A series of quinolinyl-thienyl chalcones were tested against MAO-A and B and most of them revealed potent MAO-A and B inhibition. Compound 5i exhibited most potent MAO-A inhibition activity, having IC50 value of 0.047 muM, while 4l showed maximum inhibitory potency against MAO-B having IC50 value of 0.063 muM. Molecular modelling studies were performed against human MAO-A and MAOB to rationalize most probable binding site interactions.

Process development of the synthetic route to sulamserod hydrochloride

Sulamserod hydrochloride is a potent S-HT4 receptor antagonist and was a clinical candidate for the treatment of gastrointestinal disorders. Process development of the fairly long synthetic route (12 linear, 14 overall steps) was undertaken. Process improvements were highlighted by aromatic chlorination choices in making dichlorobenzodioxan 2 and acetylaminochloroketone 7, a transfer hydrogenation reducing a nitro group and simultaneous aromatic dechlorination without ketone reduction to give aminoketone 5, and use of the potential mutagenic iodosulfonamide 14 to make quaternary salt 11. The chemistry was scaled-up into pilot plant reactor vessels to produce multikilogram amounts of Sulamserod hydrochloride suitable for drug development.

Mechanism of SmI2/amine/H2O-promoted chemoselective reductions of carboxylic acid derivatives (esters, acids, and amides) to alcohols

Samarium(II) iodide-water-amine reagents have emerged as some of the most powerful reagents (E = -2.8 V) for the reduction of unactivated carboxylic acid derivatives to primary alcohols under single electron transfer conditions, a transformation that had been considered to lie outside the scope of the classic SmI2 reductant for more than 30 years. In this article, we present a detailed mechanistic investigation of the reduction of unactivated esters, carboxylic acids, and amides using SmI2-water-amine reagents, in which we compare the reactivity of three functional groups. The mechanism has been studied using the following: (i) kinetic, (ii) reactivity, (iii) radical clock, and (iv) isotopic labeling experiments. The kinetic data indicate that for the three functional groups all reaction components (SmI2, amine, water) are involved in the rate equation and that the rate of electron transfer is facilitated by base assisted deprotonation of water. Notably, the mechanistic details presented herein indicate that complexation between SmI2, water, and amines can result in a new class of structurally diverse, thermodynamically powerful reductants for efficient electron transfer to a variety of carboxylic acid derivatives. These observations will have important implications for the design and optimization of new processes involving Sm(II)-reduction of ketyl radicals. (Chemical Equation Presented).

Non-imidazole histamine H3 ligands. Part VI. Synthesis and preliminary pharmacological investigation of thiazole-type histamine H3-receptor antagonists with lacking a nitrogen nucleus in the side chain

Background: Antagonists to the H3 receptor are considered to be potential drugs for the treatment of Alzheimer’s disease, attention deficit-hyperactive disorder, memory and learning deficits, and epilepsy. The initial development of potent H3 receptor antagonists focused on extensive modification of the natural ligand histamine. However, it has appeared that imidazole-containing ligands are associated with inhibition of cytochrome P450 enzymes, caused by imidazole nitrogen complexation to heme iron in the active site of the enzyme. For these reasons, the development of potent non-imidazole H3 receptor antagonists was eagerly awaited. Objective: Previously, we reported the synthesis and pharmacological in vitro characterization of series of potent histamine H3-receptor non-imidazole antagonists belonging to the class of substituted 2-thiazol-4-n-propylpiperazines. A lead compound 1 of this family was a derivative carrying the ethylaminomethylpropyl chain. Methods: With the aim of increasing lipophilicity, that will help the ligands to cross the blood-brain barrier, we synthesized a series of new 2-thiazol-4-n-propylpiperazines where the ethylaminomethylpropyl moiety was replaced by a p-substituted-, an unsubstituted benzene ring, and omega-phenylalkyl substituent at positions 4 and 5 of thiazole ring, respectively. All compounds were tested for H3 antagonistic effects in vitro using the electrically contracting guinea pig jejunum. Results: The most active compounds of presented series 3d, 3e, and 3j showed lower affinity than the lead compound 1 and additionally, derivatives 3d and 3j possessed weak, competitive H1-antagonistic activity. This is in contrast to the lead compound 1 that has no affinity at H1 receptor. Conclusion: We can conclude that a side chain in the 2-thiazol-4-n-propylpiperazine scaffold should contain a basic center and should be present at a favorable position 5 of thiazole ring.

HIV protease inhibitors possessing a novel, high-affinity, and achiral P1?/P2? ligand with a unique pattern of in vitro resistance. Importance of a conformationally-restricted template in the design of enzyme inhibitors

Achiral pyran-2-one analogs possessing a 3-S-(2-alkylphenyl) group were determined to be high-affinity inhibitors for human immunodeficiency virus (HIV) protease (PR). Crystallographic, modeling, and structure-activity studies led to the 3-S-(2-tert-butylphenyl) moiety as an apparent optimal group to access the S2?/S1? pockets of the enzyme. Further optimization led to an inhibitor, 3-[(2-tert-butylphenyl)sulfanyl]-4-hydroxy-6-(3-methylphenyl)-pyran-2-one (14), possessing a Ki of 3 nM. An X-ray crystallographic structure of an inhibitor, 4-hydroxy-3-[(2-isopropylphenyl)sulfanyl]-6-phenylpyran-2-one (8), bound to HIV PR showed that the 3-S-(2-isopropylphenyl) group occupied the P2? and P1? pockets, while other crucial interactions were common to those found with other pyran-2-one analogs. The high potency observed for this series may be due, in part, to the restrictions on the intramolecular collapsibility of these molecules in aqueous solution, leading to a highly favorable hydrophobic effect on binding. Herein we report a novel P2?/P1? achiral ligand which results in a tight-binding inhibitor that occupies only three pockets in the enzyme and exhibits a unique pattern of in vitro resistance.
