cyclization/allylic alkylation cascade of stable α-diazo-δ-keto-esters has been developed. Highly substituted 3(2H)-furanones with a C2-quaternary center can be obtained efficiently under mild conditions via one-pot synthesis. Remarkably, this binary catalytic system shows high chemo-, regio-, and stereoselectivity and excellent tolerance to various functionalities.
已经开发了一种协同的 Rh(II)/Pd(0) 双催化策略,可促进稳定的 α-重氮-δ-
酮酯的环化/烯丙基烷基化级联反应。通过一锅法合成,可以在温和条件下有效地获得具有 C2-季
铵盐中心的高度取代的 3( 2H )-
呋喃酮。值得注意的是,这种二元催化体系显示出高
化学、区域和立体选择性以及对各种功能的出色耐受性。
