According to “integrated chemical process”, a novel one-pot process for construction of highly substituted allylic moieties has been achieved. A series of alkylation of allylic sulfones and palladium-catalyzed reductive desulfonylation by use of LiBHEt3 is integrated. The double alkylation furnishes more substituted olefins. Use of arylzinc compounds in place of the hydride enables electrophilic a
根据“综合化学过程”,已经实现了用于构建高度取代的烯丙基部分的新颖的一锅法。整合了一系列使用LiBHEt 3进行的烯丙基砜烷基化和钯催化的还原性脱磺酰化反应。双烷基化提供更多取代的烯烃。使用芳基锌化合物代替氢化物可以在一锅中进行亲电烷基化/亲核芳基化。与相应的逐步过程相比,集成过程提供了更高的总产量。
