Abstract
A triphenylphosphinegold(I)-catalyzed cyclopropanation of olefins using propargyl esters as gold(I)-carbene precursors is reported. This reaction provided the basis for the use of a DTBM-SEGPHOS gold(I) complex as a catalyst in the enantioselective (up to 94% ee) preparation of vinyl cyclopropanes with high cis-selectivity.
摘要
报道了一种使用炔丙基酯作为金（I）-卡宾前体的三苯基膦金（I）催化的烯烃环丙烷化反应。该反应为使用DTBM-SEGPHOS金（I）配合物作为催化剂对映选择性地（对映体过量高达94%）制备具有高顺式选择性的乙烯基环丙烷提供了基础。
