A new CC bond forming reaction leading to adjacent quaternary carbons is reported. It is a one‐pot hydride shift/cyclization process facilitated by the hydricity of the acetalic CH bonds, with benzylidenemalonate fragments as electrophilic hydride acceptors, and the catalysis of scandium(III) triflate. The reaction products are 1,2‐dihydroindane derivatives. Alkoxy and alkanethiolate groups can be
报道了一种新的CC键形成反应,该反应导致相邻的季碳原子。它是由缩醛C的hydricity促进一釜氢化物转变/环化过程 H键,用benzylidenemalonate片段作为电子受体氢化物,和钪(III),三氟甲磺酸的催化作用。反应产物是1,2-二氢茚满衍生物。烷氧基和链烷硫醇酯基团也可以从缩醛碳分子内转移到亲电的亚苄基丙二酸酯CC键上。
