  Efficient Enzymatic Synthesis of Carbamates in Water Using Promiscuous Esterases/Acyltransferases

  摘要：

  Biocatalysis provides an attractive approach to facilitate synthetic reactions in aqueous media. Motivated by the discovery of promiscuous aminolysis activity of esterases, we exploited the esterase from Pyrobaculum calidifontis VA1 (PestE) for the synthesis of carbamates from different aliphatic, aromatic, and arylaliphatic amines and a set of carbonates such as dimethyl‐, dibenzyl‐, or diallyl carbonate. Thus, aniline and benzylamine derivatives, aliphatic and even secondary amines could be efficiently converted into the corresponding benzyloxycarbonyl (Cbz)‐ or allyloxycarbonyl (Alloc)‐protected products in bulk water, with (isolated) yields of up to 99 %.

• One-pot synthesis of carbamates and thiocarbamates from Boc-protected amines
  作者：Hee-Kwon Kim、Anna Lee

  日期：2016.11

  A highly efficient one-pot procedure for the synthesis of carbamates and thiocarbamates has been described. In the presence of 2-chloropyridine and trifluoromethanesulfonyl anhydride, the isocyanate intermediates were generated in situ for further reactions with alcohols and thiols to afford the desired carbamates and thiocarbamates in high yields.

  A ligand-free iron-catalyzed method for the oxygenation of benzylic sp3 C–H bonds by molecular oxygen (1 atm) using a thiyl radical as a cocatalyst has been developed. This transformation provides a facile access to amides, esters and ketones from readily accessible corresponding amines, ethers and alkanes. It features high regioselectivity, mild oxidative conditions and excellent functional group

  已开发出一种无配体的铁催化方法，该方法使用噻吩基作为助催化剂，通过分子氧（1 atm）氧化苄基sp 3 C–H键。该转化提供了从容易获得的相应的胺，醚和烷烃容易地获得酰胺，酯和酮的途径。它具有高区域选择性，温和的氧化条件和出色的官能团相容性，为复杂分子的位点选择性官能化提供了很好的机会。初步的机理研究表明，该反应可能不会经历苄基阳离子中间途径，并且产物中的羰基氧原子可能源自分子氧。

  DOI：10.1021/ol100259j

  日期：2010.3.19

  A mild and efficient library synthesis technique has been developed for the synthesis of ureas and carbamates from carbamic acids derived from the DBU-catalyzed reaction of amines and gaseous carbon dioxide. Carbamic acids derived from primary amines reacted with Mitsunobu reagents to generate isocyanates in situ which were condensed with primary and secondary amines to afford the desired ureas. Similarly

  A highly efficient metal-free oxidative α-cyanation reaction of N-acyl/sulfonyl tetrahydroisoquinolines under mild conditions was developed. The reaction uses 2,2,6,6-tetramethylpiperidine N-oxide fluoroborate salt (T+BF4−) as the oxidant and trimethylsilyl cyanide as the source of the cyano group.
