摘要

本文介绍了两种结构复杂的候选抗生素 BT-33 和链霉素的北部大环硫醇锌胺片段的可扩展合成方法。每种途径中的一个关键转化是使用锌促进的巴比尔型丙炔化协议，将一个推定的烯锌亲核体与常见的埃尔曼亚磺酰亚胺中间体进行高非对映选择性加成，本文将对此进行详细介绍。这些转化过程具有动态动力学分辨率，且每种丙炔基溴化物前体的用量仅为 1.2 等量。

Practical Synthesis of Macrobicyclic Thiolincosamines

Scalable syntheses of the northern macrobicyclic thiolincosamine fragments of two structurally complex antibiotic candidates, BT-33 and cresomycin, are presented. A key transformation in each route is the highly diastereoselective addition of a putative allenylzinc nucleophile to a common Ellman sulfinimine intermediate using a zinc-promoted Barbier-type propargylation protocol that is detailed herein. These transformations proceed with dynamic kinetic resolution and use just 1.2 equiv of each respective propargyl bromide precursor.
