Highly stereoselective alkylative and arylative cyclization reactions of allenyl-aldehydes and -ketones with organozinc reagents occur efficiently in the presence of catalytic Ni(COD)2 to afford cis-fused homoallylic cyclopentanols.
在催化Ni(COD)2的存在下,烯丙基-醛和-酮与
有机锌试剂的高度立体选择性烷基化和芳基化环化反应可有效发生,以提供顺式稠合均烯丙基
环戊醇。
