Ab. Charette et al., THE CHEMOSELECTIVE AND ENANTIOSELECTIVE CYCLOPROPANATION OF POLYENES - CHIRAL AUXILIARY VS CHIRAL REAGENT-BASED APPROACH, Tetrahedron letters, 37(44), 1996, pp. 7925-7928
The chemo- and enantioselective cyclopropanation of allylic alcohols c
ontaining additional olefins was investigated using the dioxaborolane-
derived reagent. High chemo- and enantioselectivities were usually obs
erved if a mixture of the chiral dioxaborolane ligand/allylic alcohol
was treated with a solution of Zn(CH2I)(2) . DME complex. Copyright (C
