The first enantioselective Friedel-Crafts alkylation-acetalization-cascade of naphthols with alpha,beta-unsaturated cyclic ketones and 1H-inden-1-ones was realized. 9-Amino(9-deoxy)epi-quinine A was the catalyst of choice for the realization of polycyclic structures with high enantiocontrol.
首次实现了萘酚与α,β-不饱和环酮和1H-茚-1-酮的对映选择性Friedel-Crafts烷基化-缩醛化级联反应。9-氨基(9-脱氧)表奎宁A是实现高对映体控制的多环结构的选择催化剂。
