  通过有机硼烷合成埃博霉素A的研究。

  摘要：

  已经描述了通过有机硼烷合成埃坡霉素A的研究。已开发出一种从异戊烯醇大规模制备B-γ，γ-二甲基烯丙基亚砜基樟脑基硼烷的改进方法。与各种醛反应后，该试剂以高对映选择性提供相应的α，α-二甲基均烯丙基醇。已经证明了该试剂在合成埃博霉素的C1-C6亚基中的应用。或者，分子间和分子内不对称还原方案也已用于合成埃坡霉素A的C1-C6亚基。使用α-pine烯衍生的试剂合成埃坡霉素A的C7-C21片段，涉及不对称烷氧基烯丙基和巴豆基硼化也已经描述过了。

  A preparative-scale synthesis of B-gamma,gamma-dimethylallyldissopinocampheylborane starting from prenyl alcohol has been described. This reagent, upon reaction with various aldehydes, provides the corresponding alpha,alpha-dimethylhomoallylic alcohols in high enantioselectivities. The application of this reagent has been demonstrated for the synthesis of C-1-C-6 Subunit of epothilone. (C) 2003 Elsevier Ltd. All rights reserved.

  日期：1992.1

  Benzoyl-pedamide (2) a key building block for the synthesis of pederin, has been synthesized in 13 steps from malic acid. The new stereogenic centers have been generated under reagent control of diastereoselectivity with selectivities of 87 and 80% using the newly developed chiral alpha-substituted allylboronate 16 as well as 21 as reagents.
