We have developed an expedient method for the synthesis of polycyclic compounds from propargyl acetates or vinyl allenes involving up to three Au(I)-catalyzed elemental steps: 3,3-rearrangement, metalla-Nazarov reaction, and electrophilic cyclopropanation. The reaction proceeds under very mild conditions and in short times. The mechanism has been studied by DFT computations.
我们已经开发了一种从醋酸炔丙酯或乙烯基丙二烯合成多环化合物的简便方法,涉及多达三个Au(I)催化的元素步骤:3,3-重排,metalla-Nazarov反应和亲电子环丙烷化。反应在非常温和的条件下并在短时间内进行。已经通过DFT计算研究了该机制。
