Catalyst debut: The chiral ammonium betaine 1 has been successfully applied to the asymmetric Steglich rearrangement as an ionic nucleophilic catalyst. The catalyzed reaction results in record levels of product enantioselectivity, and has a broad substrate scope. M.S.=molecular sieves, Troc=2,2,2‐trichloroethoxycarbonyl.
催化剂首次亮相:手性铵甜菜碱1已成功地作为离子型亲核催化剂应用于不对称Steglich重排。催化反应导致产物对映选择性达到创纪录水平,并具有广泛的底物范围。MS =分子筛,Troc = 2,2,2-三氯乙氧羰基。
