  Angiotensin-converting enzyme inhibitors. Perhydro-1,4-thiazepin-5-one derivatives

  摘要：

  alpha-[6-[[(S)-1-(Ethoxycarbonyl)-3-phenylpropyl]amino]-5-oxoperhydro -1,4-thiazepin-4-yl]acetic acids (monoester monoacids) and their dicarboxylic acids having the hydrophobic substituents at the 2- or 3-position of the thiazepinone ring were prepared and assayed for angiotensin-converting enzyme (ACE) inhibitory activity. The dicarboxylic acids having the pseudoequatorial amino groups at the 6-position and the pseudoequatorial hydrophobic substituents at the 2- or 3-position of the chair conformation of the thiazepinone ring had potent in vitro inhibitory activity. The monoester monoacids having the hydrophobic substituents at the 2-position suppressed pressor response to angiotensin I for a longer duration than those having the substituents at the 3-position when administered orally. The structure-activity relationship was studied by conformational energy calculations of the thiazepinone ring.

• Cyanide-Free and Broadly Applicable Enantioselective Synthetic Platform for Chiral Nitriles through a Biocatalytic Approach
  作者：Tobias Betke、Philipp Rommelmann、Keiko Oike、Yasuhisa Asano、Harald Gröger

  DOI：10.1002/anie.201702952

  日期：2017.9.25

  A cyanide‐free platform technology for the synthesis of chiral nitriles by biocatalytic enantioselective dehydration of a wide range of aldoximes is reported. The nitriles were obtained with high enantiomeric excess of >90 % ee (and up to 99 % ee) in many cases, and a “privileged substrate structure” with respect to high enantioselectivity was identified. Furthermore, a surprising phenomenon was observed

Pentaerythritol tetranitrate reductase (PETN reductase) from Enterobacter cloacae st. PB2 catalyses the reduction of nitroolefins such as 1-nitrocyclohexene (1) with steady state and rapid reaction kinetics comparable to other old yellow enzyme

• Organocatalytic, Enantioselective Conjugate Addition of Nitroalkanes to Nitroolefins
  作者：Jian Wang、Hao Li、Liansuo Zu、Wei Jiang、Wei Wang

  An organocatalytic, enantioselective conjugate addition reaction of nitroalkanes with nitroolefins has been developed under neat conditions without using an organic solvent. The process, catalyzed by a modified Cinchona alkaloid, affords synthetically useful 1,3-dinitro compounds in good yields (70–82 %) with good degrees of enantioselectivity (67–88 % ee).

• Indole-to-Carbazole Strategy for the Synthesis of Substituted Carbazoles under Metal-Free Conditions
  作者：Shanping Chen、Yuxia Li、Penghui Ni、Huawen Huang、Guo-Jun Deng

  日期：2016.10.21

  An efficient indole-to-carbazole strategy has been developed under metal-free conditions. This carbazole formation was highly promoted by NH4I with high regioselectivity through formal [2 + 2 + 2] annulation of indoles, ketones, and nitroolefins. It thus conveniently enabled the assembly of a large number of diversified carbazole products with good tolerance of a broad range of functional groups.

  4-triaryl-substituted pyrrole products were obtained in good to high yields. Furthermore, 2,3,5-triaryl-substituted pyrroles were selectively formed in the absence of nitrovinylarenes. The photophysical properties of some pyrrole products have been investigated to show good aggregation-induced emission (AIE) activity.
