N-(4-Substituted-thiazolyl)oxamic Acid Derivatives, a New Series of Potent, Orally Actve Antiallergy Agents

A series of N-(4-substituted-thiazolyl)oxamic acid derivatives were synthesized and tested for antiallergy activity in the rat PCA model.These compounds were conveniently prepared by treatment of the appropriate acetophenone with thiourea and iodine or by reaction of the chloroacetylbenzene with thiourea to give the corresponding aminothiazoles; subsequent condensation with ethyloxalyl chloride gave the thiazolyloxamates.Many of the analogues showed a 50percent inhibition at <2 mg/kg po or <0.4 mg/kg iv and were significantly more potent than disodium cromoglycate, which in the rat PCA mode l is orally inactive and gives a 50percent inhibition at 1.2 mg/kg iv.Hydrolysis of the oxamates generally resulted in enhanced activities, while substitution of the phenyl ring with a variety of substituents (e.g.,4-F, 4-OEt, and 4-NHCOCH3) did not significantly enhance the activity of the unsubstituted phenyl derivative.One of the ethanolamine salts, N-<4-(1,4-benzodioxan-6-yl)-2-thiazolyl>oxamic acid ethanolamine salt (61, PRH-836-EA), has been selected for further pharmacological evaluation.

Chiral Br¡ãnsted Acid from Chiral Phosphoric Acid Boron Complex and Water: Asymmetric Reduction of Indoles

A new chiral Br¡ãnsted acid, generated in situ from a chiral phosphoric acid boron (CPAB) complex and water, was successfully applied to asymmetric indole reduction. This ?designer acid catalyst?, which is more acidic than TsOH as suggested by DFT calculations, allows the unprecedented direct asymmetric reduction of C2-aryl-substituted N-unprotected indoles and features good to excellent enantioselectivities with broad functional group tolerance. DFT calculations and mechanistic experiments indicates that this reaction undergoes C3-protonation and hydride-transfer processes. Besides, bulky C2-alkyl-substituted N-unprotected indoles are also suitable for this system.

Synthesis of 5-Aryl-3(2 H)-furanones Using Intramolecular Cyclization of Sulfonium Salts

Base-induced intramolecular cyclization of novel (4-aryl-2,4-dioxobutyl)methylphenylsulfonium salts prepared from the commercially available 1-arylethanone by a cost-effective process is described in this paper. The reaction was completed within 10 min to produce a family of 2-unsubstituted 5-aryl-3(2H)-furanones in excellent yield. This procedure is simple, and can be carried out under mild conditions and an ambient atmosphere.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety of 1-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)ethanone, you can also check out more blogs about2879-20-1

Aerobic oxidative alpha-iodination of carbonyl compounds using molecular iodine activated by a nitrate-based catalytic system

The novel reaction system comprising air/NH4NO3(cat.)/I2/H2SO4(cat.)is introduced as a simple, safe, cheap, efficient, and regioselective mediator for direct aerobic oxidative alpha-iodination of aryl, heteroaryl, alkyl, and cycloalkyl methyl ketones. The reaction system enabled the moderate to quantitative regioselective iodination of a large range of different methyl ketone derivatives including those bearing oxidizable heteroatom (S, N) substituents. Several activated aromatic compounds were also efficiently and selectively iodinated. The practical applicability of the presented reaction system was shown on 20 mmol scale under ambient pressure and 100% conversion of substrate was achieved.

Pyrrolidine-3-carboxylic acids as endothelin antagonists. 2. Sulfonamide-based ET(A)/ET(B) mixed antagonists

When the N,N-dialkylacetamide side chain of the highly ET(A)-selective endothelin antagonist ABT-627 (1; [2R,3R,4S]-2-(4-methoxyphenyl)-4-(1,3- benzodioxol-5-yl)-1-[[(N,N-dibutylamino)carbonyl]methyl]pyrrolidine-3- carboxylic acid; A-147627) is replaced by N,S-dialkylsulfonami-doethyl, the resultant analogs retain ET(A) affinity, but exhibit substantial ET(B) affinity as well. Structure-activity studies reveal that modifications in the length of the two alkyl groups, and in the substitution on the anisyl ring, are important in optimizing this ‘balanced’ antagonist profile. In particular the combination of an N-n-propyl group, an S-alkyl chain between four and six carbons in length, and a fluorine atom ortho to the aromatic OCH3 provides compounds with sub-nanomolar affinities for both receptor subtypes, and with ET(A)/ET(B) ratios close to 1. A number of these compounds also exhibit oral bioavailabilities (in rats) in the 30-50% range and have substantial plasma half-lives. The balanced receptor-binding profile of these potent and orally bioavailable compounds complements the ET(A) selectivity observed with 1.

Easy Access to 1-Amino and 1-Carbon Substituted Isoquinolines via Cobalt-Catalyzed C – H/N – O Bond Activation

A green atom-economical method for the synthesis of highly functionalized 1-amino and 1-carbon substituted isoquinolines from the reaction of N?-hydroxybenzimidamides and aryl ketoximes, respectively, with alkynes via pentamethylcyclopentadienylcobalt(III)-catalyzed C – H/N – O bond activation is described. The external oxidant-free annulation reaction uses the =NOH moiety in N?-hydroxybenzimidamides or N-aromatic ketone oximes as the directing group and internal oxidant. This first row transition metal-catalyzed annulation serves as an efficient alternative for the synthesis of isoquinolines, as water is the only by-product and expensive noble metals such as rhodium(III), iridium(III), palladium(II), and ruthenium(II) are not required. The reaction proceeds via C – H activation, alkyne insertion, reductive elimination, and N – O activation.

Iron-catalyzed C[sbnd]C bond activation/C[sbnd]O bond formation: Direct conversion of ketones to esters

The iron-catalyzed oxidative activation of the (O)C[sbnd]C bond in ketones has been developed. This method enables direct synthesis of esters by the reaction between ketones and alcohols via conversion of the (O)C[sbnd]C bond to the (O)C[sbnd]O bond. The reaction runs selectively: the (O)C[sbnd]CAlkyl bond is activated, while the (O)C[sbnd]CAryl bond remains intact (i.e., iron-catalyzed intermolecular anti-Baeyer-Villiger activation of the (O)C[sbnd]C bond). The reaction conditions are carefully optimized and allow the production of esters with yields of up to 95%. The method is based on the inexpensive and commercially available catalyst (FeCl3), oxidant ((NH4)2S2O8), and solvent (DCE) without using any ligands or additives.

Direct synthesis of ethers from aldehydes and ketones. One-pot reductive etherification of benzaldehydes, alkyl aryl ketones, and benzophenones

Benzyl alcohols formed by the reduction of benzaldehydes, alkyl aryl ketones, and benzophenones with sodium tetrahydridoborate in alcohols undergo in situ etherification with the solvent in the presence of a catalytic amount of HCl. Thus the process may be regarded as one-pot transformation of carbonyl compounds into the corresponding benzyl ethers. The yields of ethers depend on the substituent nature in the aromatic fragment of the initial carbonyl compound and on the alcohol used as reduction medium.
