Alkynylaluminum reagents undergo enantioselective conjugate addition to cyclic alpha,beta-enones In the presence of chiral bisphosphine complexes of Ni(II).
Trends in Organocatalytic Conjugate Addition to Enones: An Efficient Approach to Optically Active Alkynyl, Alkenyl, and Ketone Products
Three in one: Applying an organocatalytic tandem strategy to build a library of opticallyactive alkynyl, alkenyl, and ketone products, starting from cyclic enones and β‐keto sulfones, is shown to be rapid and efficient (see scheme; R=aryl, R′=H or alkyl).
三合一:从环烯酮和β-酮砜开始,应用有机催化串联策略建立光学活性炔基,烯基和酮产物的库是快速有效的(请参阅方案; R =芳基,R '= H或烷基)。
