  Efficient chemoselective deprotection of silyl ethers using catalytic 1-chloroethyl chloroformate in methanol

  摘要：

  Fast and chemoselective desilylation of silyl-protected alcohols was achieved using a catalytic amount of 1-chloroethyl chloroformate in methanol. With a minimal amount of 1-chloroethyl chloroformate as the source for anhydrous HCl, extremely efficient cleavage of silyl ethers of primary and secondary alcohols was accomplished, and chemoselective deprotection of one silyl ether in the presence of another silyl or other acid-labile group was possible through controlling the amount of the chloroformate and reaction time.

• Anaerobic Nitroxide-Catalyzed Oxidation of Alcohols Using the NO⁺/NO· Redox Pair
  作者：Martin Holan、Ullrich Jahn

  DOI：10.1021/ol403016p

  日期：2014.1.3

  A new method for alcohol oxidation using TEMPO or AZADO in conjunction with BF3·OEt2 or LiBF4 as precatalysts and tert-butyl nitrite as a stoichiometric oxidant has been developed. The system is based on a NO+/NO· pair for nitroxide reoxidation under anaerobic conditions. This allows the simple, high-yielding conversion of various achiral and chiral alcohols to carbonyl compounds without epimerization

  开发了一种新的醇氧化方法，该方法使用TEMPO或AZADO结合BF 3 ·OEt 2或LiBF 4作为预催化剂，并使用亚硝酸叔丁酯作为化学计量的氧化剂。该系统基于NO + / NO·对，用于厌氧条件下的氮氧化物再氧化。这允许各种非手性和手性醇简单，高产率地转化为羰基化合物，而没有差向异构化，并且不形成非挥发性副产物。
