Stereoselective Functionalization of β-Iodo-α,β-Unsaturated Ketones via an Iodine−Copper Exchange Reaction
摘要:
beta-lodo-alpha,beta-unsaturated carbonyl compounds undergo a stereoselective iodine-copper exchange reaction with (Nphyl)(2)CuLi, providing the corresponding alkenyl cuprates with retention of the double bond configuration. No competitive addition/elimination was observed, and the resulting cuprates were successfully functionalized with various electrophiles.
