Abstrakt: The chemo- and enantioselective cyclopropanation of allylic alcohols containing additional olefins was investigated using the dioxaborolane-derived reagent. High chemo- and enantioselectivities were usually observed if a mixture of the chiral dioxaborolane ligand/allylic alcohol was treated with a solution of Zn(CH 2I) 2·DME complex.
