摘要: Asymmetric annulation of allenes with electron-deficient olefins and imines is one the most important reactions for synthesis optically active carbo- heterocycles, which are useful building blocks natural products medicinally substances. The use chiral phosphines as enantioselective catalysts can be envisaged such cyclizations. This article focuses on developments concerning asymmetric annulations unsaturated partners in recent decades perspectives that these new offer.
