Enantioselective Michael addition of simple 3(2H)-furanones to α,β-unsaturated aldehydes has been described. The protocol provides a simple and efficient access to complex 3(2H)-furanones containing adjacent quaternary and tertiary stereocenters in high yields with moderate diastereoselectivities and excellent enantioselectivities.
已经描述了简单的3(2 H)-呋喃酮向α,β-不饱和醛的对映选择性迈克尔加成。该协议以高收率,适度的非对映选择性和出色的对映选择性,提供了一种简单高效的途径,可轻松获取包含相邻四级和三级立体中心的复杂3(2 H)呋喃酮。
