Functionalized allylic electrophilicreagents such as chiral 2-iodo-1-cyclohexenyl and -cyclopentenyl phosphates undergo highly stereoselective anti-S(N)2'-allylic substitution reactions with a wide range of organozinc reagents (R(2)Zn and RZnI) leading to chiral products with a transfer of the chiral information >95%. The use of functionalized organozinc iodides allows preparation of the bicyclic enones
