Reaction of ethyl 2-(sulfonylmethyl)- or 2-(cyanomethyl)allyl carbonate with α,β-unsaturated esters or ketones in the presence of PD2(dba)3·.CHCl3-dppe catalyst gave highly functionalized cyclopentanes regio-selectively in good yields.
在PD 2(dba)3 ·.CHCl 3 -dppe催化剂存在下,乙基2-(磺酰基甲基)-或2-(氰基甲基)烯丙基碳酸酯与α,β-不饱和酯或酮反应,可选择性地高度官能化环戊烷丰产。
