Easy and efficient: By applying the title transformation, two adjacent sp3 stereogenic centers, one of which is a quaternary carbon center, can be easily formed. This asymmetric reaction provides easy and efficient access to multifunctionalized tetrahydropyrrole, tetrahydrofuran, and cyclopentane compounds (see scheme; coe=cyclooctene, DME=1,2‐dimethoxyethane, Tf=trifluoromethanesulfonyl).
简单高效:通过应用标题转换,可以轻松地形成两个相邻的sp 3立体中心,其中一个是季碳中心。这种不对称反应可轻松有效地获得多官能化的四氢吡咯,四氢呋喃和环戊烷化合物(请参阅示意图; coe =环辛烯,DME = 1,2-二甲氧基乙烷,Tf =三氟甲磺酰基)。
