Grignard reagents derived from IC6H4R (R = CO2Et, CN, CH2OAc, CH(2)OPiv, I) and i-PrMgCl were subjected to CuCN-catalyzed allylic substitution of the monoacetate at 0 degrees C for one hour to furnish the anti-S(N)2' products regio- and stereoselectively. The ester group at the ortho-position did not affect the substitution.
