A versatile route to trisubstituted alkenylstannanes is presented. The alkyl and Sn moieties were introduced at the β and α carbon atoms of alkynoates, respectively, in a formal syn addition mode with complete regioselectivity (see scheme). A variety of functional groups were tolerated in the alkylboranes and alkynoates.
提出了一种通用的途径来制备三取代的链烯基锡烷。烷基和Sn部分分别以正式的顺式 加成模式和完全的区域选择性引入炔烃的β和α碳原子上(参见方案)。烷基硼烷和炔酸酯中可耐受多种官能团。
