A chiral all-carbon tetrasubstituted VQM is generated by chiral phosphoric acid catalyzed nucleophilic addition of 2-alkynylnaphthols to o-quinone methides or imines, and it can be captured intramolecularly by a cycloaddition reaction. A wide range of naphthyl-2H-chromenes bearing axially and centrally chiral elements and axially chiral quinone-naphthols were prepared efficiently with excellent enantioselectivities
手性全碳四取代 VQM 是由手性磷酸催化的 2-炔基萘酚与邻醌甲基化物或亚胺的亲核加成生成的,并且可以通过环加成反应在分子内捕获。以优异的对映选择性有效制备了多种带有轴向和中心手性元素的萘基-2 H-色烯和轴向手性醌-萘酚。
