Novel one-pot synthesis of 1-iodo-1-trimethylsilyl 1,3-dienes
Abstract
Iodine was added to 3-(trimethylsilyl )allylic phosphonium ylide regiospecifically to give 3-iodo-3-trimethylsilyl allylic phosphonium ylide, which reacted with carbonyl compounds to give 1-iodo-1-trimethylsilyl 1,3-dienes with high stereoselectivity in good yield.
