A Chemoenzymatic Total Synthesis of ent-Bengamide E
摘要:
The cis-1,2-dihydrocatechol 3, which can be obtained in enantiomerically pure form by microbial dihydroxylation of bromobenzene, has been converted into the enantiomer, ent-1, of the cyclolysine-based marine natural product bengamide E (1).

A modular, eight-step synthesis of bengamideE and six analogues from a common chiral pool has been developed. The key step in this approach is a cross-metathesis coupling of various commercial terminal olefins and a common alkene bearing the required stereogenic centers of bengamides lateral chain, which was easily derived from α-D-glucoheptonic-γ-lactone. Complete E-selectivity, and up to 92% yield
已经开发了一种模块化的八步合成苯甲酰胺 E 和来自共同手性池的六种类似物。这种方法的关键步骤是将各种商业末端烯烃和带有所需的苯甲酰胺侧链立体中心的普通烯烃进行交叉复分解偶联,这很容易从α-D-葡萄糖庚酸-γ-内酯衍生而来。这一关键的交叉复分解步骤实现了完全的 E 选择性和高达 92% 的产率。

The synthesis of the non-natural antipode of the bengamide polyol-containing side chain has been achieved utilizing a diastereoselective oxygenated-enolate aldol reaction as the key step. A substrate-controlled reduction was used to complete the stereochemical array. (C) 2007 Elsevier Ltd. All rights reserved.
