The first facile, efficient, atom-economical and regioselective palladium-catalyzed direct C–P cross-coupling of unprotected allenic alcohols with H-phosphonates for the one-pot synthesis of structurally diverse multisubstituted 2-phosphinoyl-1,3-butadienes was developed. This strategy would enrich the allene chemistry and afford new scaffolds to construct complex molecular skeletons.
开发了第一种简便,有效,原子经济和区域选择性的钯催化的未保护的烯丙醇与H-膦酸酯的直接C-P交叉偶联,用于单锅合成结构多样的多取代的2-膦酰基-1,3-丁二烯。这种策略将丰富异戊二烯的化学反应,并为构建复杂的分子骨架提供新的支架。
