A five-step assembly of silicon-protected dipeptide mimics from commercially available reagents is described. This methodology makes silanediol protease inhibitors readily available for the first time. The sequence features asymmetric hydrosilylation, a novel reduction of a silyl ether to a silyllithium reagent, and addition of this dianion to a sulfinimine, to produce the complete inhibitor skeleton
描述了来自市售试剂的硅保护二肽模拟物的五步组装。这种方法使硅烷二醇蛋白酶抑制剂首次易于获得。该序列具有不对称氢化硅烷化、甲硅烷基醚到甲硅烷基锂试剂的新还原以及该二价阴离子与亚磺亚胺的加成,以产生完全控制立体化学的完整抑制剂骨架。伯醇氧化成酸完成合成。
