Highly Stereoselective Anti SN2‘ Substitutions of (Z)-Allylic Pentafluorobenzoates with Polyfunctionalized Zinc−Copper Reagents
摘要:
[GRAPHICS]Allylic substitution reactions of zinc-copper organometallics on (Z)-allylic pentafluorobenzoates proceed with very high regioselectivity and excellent anti selectivity. The high fidelity in transfer of stereochemical information allowed a short synthesis of (+)-ibuprofen (97% ee).
