Efficient Synthetic Method of Z-Selective 2-Halo-1,3-dienes from Reactions of Allenols Possessing Ethoxycarbonyl and Vinyl Group with Indium Trihalide

摘要

An efficient synthetic method of Z-selective 3-ethoxycarbonyl-2-halo-1,3-dienes and 3-vinyl-2-halo-1,3-dienes was developed from the reaction of allenols having ethoxycarbonyl and vinyl group with indium trihalides at room temperature in CH2Cl2.
