generation of α‐thiomethyllithium reagents via reductive lithiation or deprotonation followed by reaction with variously functionalized Weinreb amides represents an excellent method to access β‐oxo thioethers. The procedure is adaptable to alkyl‐ or aryl‐ thiomethyllithium conjugates. It has the advantages of conceptual simplicity and versatility of the addition of organometallics to Weinreb amides with the
通过还原锂化或去质子化,然后与各种功能化的Weinreb酰胺反应,可以正确生成α-硫代甲基锂试剂,这是获得β-氧代硫醚的绝佳方法。该程序适用于烷基或芳基硫代甲基锂共轭物。它具有概念简单性和向Weinreb酰胺中添加有机金属化合物的多功能性,并有可能完全保留起始材料中包含的光学信息。
