Highly rapid and direct synthesis of monoacylated piperazine derivatives from carboxylic acids under mild conditions

A series of monoacylated piperazine derivatives were obtained by the reaction of carboxylic acids with 2-chloro-4,6-dimethoxy-1,3,5-triazine in dichloromethane at room temperature. Good to excellent yields, short reaction times and mild reaction conditions are important features of this methodology.

Cyclic Iodine Reagents Enable Allylic Alcohols for Alkyl Boronate Addition/Rearrangement by Photoredox Catalysis

All-carbon quaternary centers are prevalent in bioactive small molecules. However, their efficient construction remains a formidable synthetic challenge. Here we report cyclic iodine(III) reagents enable the synthesis of cyclopentanones, cyclohexanones, and dihydrofuranones bearing alpha-quaternary centers by photoredox catalysis. The reaction proceeds by the formation of the novel cyclic iodine(III) reagent-allylic alcohol complex, which enables the first alkyl boronate addition and semi-pinacol rearrangement of allylic alcohols with dual alcohol and olefin activation. The reaction is suitable for gram scale synthesis and is transformable to alcohols, olefins, oximes, and lactones with an alpha-quaternary center in one step.

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.Recommanded Product: (2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)methanol, you can also check out more blogs about39270-39-8

Near-Infrared Photoswitching of Azobenzenes under Physiological Conditions

Biological tissue exhibits an absorbance minimum in the near-infrared between 700 and 900 nm that permits deep penetration of light. Molecules that undergo photoisomerization in this bio-optical window are highly desirable as core structures for the development of photopharmaceuticals and as components of chemical-biological tools. We report the systematic design, synthesis, and testing of an azobenzene derivative tailored to undergo single-photon photoswitching with near-infrared light under physiological conditions. A fused dioxane ring and a methoxy substituent were used to place oxygen atoms in all four ortho positions, as well as two meta positions, relative to the azobenzene N=N double bond. This substitution pattern, together with a para pyrrolidine group, raises the pKa of the molecule so that it is protonated at physiological pH and absorbs at wavelengths >700 nm. This azobenzene derivative, termed DOM-azo, is stable for months in neutral aqueous solutions, undergoes trans-to-cis photoswitching with 720 nm light, and thermally reverts to the stable trans isomer with a half-life near 1 s.

Iron-Catalyzed Borrowing Hydrogen beta- C(sp3)-Methylation of Alcohols

Herein we report the iron-catalyzed beta-C(sp3)-methylation of primary alcohols using methanol as a C1 building block. This borrowing hydrogen approach employs a well-defined bench-stable (cyclopentadienone)iron(0) carbonyl complex as precatalyst (5 mol %) and enables a diverse selection of substituted 2-arylethanols to undergo beta-C(sp3)-methylation in good isolated yields (24 examples, 65% average yield).

Discovery of novel guanidinophenylpyrazole human acrosin inhibitors by molecular hybridization

Human acrosin is a promising target for male contraceptives. A series of novel guanidinophenylpyrazole derivatives were rationally designed by molecular hybridization of the phenylpyrazole and guanidinobenzoate inhibitors. Most of the target compounds showed potent human acrosin inhibitory activities. In particular, compound F3 was a highly active human acrosin inhibitor (IC50 = 1.26 muM) with good selectivity over trypsin. Molecular docking studies revealed that compound F3 formed hydrophobic and hydrogen bonding interactions with the active site of human acrosin. Compound F3 represents a promising lead compound for the development of novel male contraceptives.

A set of 1-(arylalkyl)quinolizidines, isosteric thioanalogues, and variously functionalized congeners were synthesized (see 1-25) and tested for affinity to sigma 1 and sigma 2 receptor subtypes, by displacing [ 3H]- (+)-pentazocine and [3H]DTG from guinea pig brain and rat brain preparations, respectively. All compounds exhibited a good affinity for the sigma1 subtype, with subnanomolar Ki values for the best of them, while only modest or poor affinity for the sigma2 subtype was observed (Tables 1 and 2). Some structure-activity relationships were put forward.

Biocatalytic Formal Anti-Markovnikov Hydroamination and Hydration of Aryl Alkenes

Biocatalytic anti-Markovnikov alkene hydroamination and hydration were achieved based on two concepts involving enzyme cascades: epoxidation-isomerization-amination for hydroamination and epoxidation-isomerization-reduction for hydration. An Escherichia coli strain coexpressing styrene monooxygenase (SMO), styrene oxide isomerase (SOI), omega-transaminase (CvTA), and alanine dehydrogenase (AlaDH) catalyzed the hydroamination of 12 aryl alkenes to give the corresponding valuable terminal amines in high conversion (many ?86%) and exclusive anti-Markovnikov selectivity (>99:1). Another E. coli strain coexpressing SMO, SOI, and phenylacetaldehyde reductase (PAR) catalyzed the hydration of 12 aryl alkenes to the corresponding useful terminal alcohols in high conversion (many ?80%) and very high anti-Markovnikov selectivity (>99:1). Importantly, SOI was discovered for stereoselective isomerization of a chiral epoxide to a chiral aldehyde, providing some insights on enzymatic epoxide rearrangement. Harnessing this stereoselective rearrangement, highly enantioselective anti-Markovnikov hydroamination and hydration were demonstrated to convert alpha-methylstyrene to the corresponding (S)-amine and (S)-alcohol in 84-81% conversion with 97-92% ee, respectively. The biocatalytic anti-Markovnikov hydroamination and hydration of alkenes, utilizing cheap and nontoxic chemicals (O2, NH3, and glucose) and cells, provide an environmentally friendly, highly selective, and high-yielding synthesis of terminal amines and alcohols.
