details the preparation of three compounds which are structurally designed to have depressed metabolism and/or conjugation: 2,4-dibromo-, 2,4-dichloro-, and 2,4-dimethyl-17 alpha-iodovinylestradiol. Their synthesis includes the use of two novel transformations based upon tin chemistry: preparation of an intermediate 17 alpha-vinylstannanes via stannylcupration of a 17 alpha-ethynyl steroid, and preparation
该报告详细介绍了三种在结构上设计成代谢和/或结合抑制的化合物的制备:2,4-二溴-,2,4-二氯-和2,4-二甲基-17α-碘乙烯基雌二醇。他们的合成方法包括使用基于锡化学的两种新型转化方法:通过17α-乙炔基甾类的苯乙烯化制备中间体17α-乙烯基stannanes,以及通过钯催化的2偶联反应制备2,4-二甲基官能度。乙酸4-二溴雌酮与四甲基锡。还描述了这三种材料的制备放射化学。
