An unprecedented rearrangement of 1,2‐bis(sulfone)vinylenes used in aminocatalysis led to the formation of highly useful gem‐disulfones (see scheme). By using aminal–pyrrolidine organocatalysts, the 1,2‐sulfone shift was generalised, leading to highly versatile adducts using both ketones and aldehydes. It represents a valuable alternative for the α‐alkylation of carbonyl compounds.
氨基催化中使用的1,2-双(砜)亚乙烯基的前所未有的重排导致形成了非常有用的宝石-二砜(请参见方案)。通过使用氨基-吡咯烷有机催化剂,可以实现1,2-砜的转变,从而导致使用酮和醛的通用性高的加合物。它代表了羰基化合物的α-烷基化的一种有价值的替代方法。
