摘要

Catalytic processes that form functionalized cyclic molecules represent a key transformation for synthetic organic chemistry.[1, 2] Recently, a number of organocatalytic processes have emerged that often provide excellent levels of both enantioand diastereocontrol for the synthesis of cyclic molecules.[3, 4] Our recent studies have identified the utility of ammonium ylides for carbon–carbon bond formation. Herein we describe the development of a new ...
