  Regioselective and Stereospecific Azidation of 1,2- and 1,3-Diols by Azidotrimethylsilane via a Mitsunobu Reaction

  摘要：

  A one-pot regio- and stereospecific azidation reaction of 1,2- and 1,3-diols with azidotrimethylsilane (Me3SiN3) via a Mitsunobu reaction has been achieved. With 1,2- and 1,3-diols, the reaction of triphenylphosphine, diisopropyl azodicarboxylate, and Me3SiN3 in dichloromethane gave regioselective azidation at C-2 and C-3, respectively, in good yield (74-90% combined yield of 1a + 1b or of 2a + 2b). However, application of the same reaction conditions to a 1,4-diol led to the exclusive formation of the cyclic ether. The regioselectivity of this one-pot reaction is influenced by the solvent, the degree of steric bulk at C-2 of the 1,2-diol or at C-3 of the 1,3-diol, and the presence of electron-donating and electron-withdrawing groups near the secondary carbinol carbon. This selectivity is discussed in terms of the mechanistic model proposed by Mathieu-Pelta and Evans (Mathieu-Pelta, I.; Evans, S. A., Jr. J. Org. Chem. 1898, 57, 3409-3413), which involves reaction of the dioxaphospholane intermediate with Me3SiN3 to form oxyphosphonium ions 4 and 5.

  one-pot reaction sequence starting from prochiral α-chloroketones leading to enantiopure β-azidoalcohols and β-hydroxynitriles is described. Asymmetric bioreduction of α-chloroketones by hydrogen transfer catalysed by an alcohol dehydrogenase (ADH) established the stereogenic centre in the first step to furnish enantiopure chlorohydrin intermediates. Subsequent biocatalysed ring closure to the epoxide

  描述了从前手性 α-氯酮开始导致对映纯 β-叠氮醇和 β-羟基腈的三步、两酶、一锅反应序列。通过由醇脱氢酶 (ADH) 催化的氢转移对 α-氯酮进行不对称生物还原，在第一步中建立了立体中心，以提供对映纯的氯醇中间体。随后通过非选择性卤代醇脱卤酶 (Hhe) 催化环氧化物的生物催化闭环和用叠氮化物 N3- 或氰化物 CN- 的亲核开环进行完全保留构型，得到对映体纯的 β-叠氮醇和 β-羟基腈，分别。合成了各种光学纯 β-叠氮醇和 β-羟基腈的两种对映异构体。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
