A Pd-catalyzed hydrophosphinylation of alkyl and aryl-oxyallenes with phosphine oxides has been developed for the efficient and rapid construction of a family of chiral allylic phosphine oxides with a diverse range of functional groups. This methodol. was further applied in the facile construction of chiral 2H-chromene and later stage functionalization of cholesterol.
