3.0]deca-1,7-dien-9-one ring system by rhodium-catalyzed Pauson-Khand reaction (PKR) of allenynes with a sulfonyl group has been developed. Investigation of the rhodium-catalyzed PKR on 19 examples of 1,2-nonadien-8-yne derivatives demonstrated that (i) acceptable yields could be consistently achieved through the proper choice of the rhodium catalyst ([RhCl(CO)(2)](2) or [RhCl(CO)dppp](2)) depending
已经开发出了一种可靠的方法,该方法可通过铑催化带有磺酰基的烯丙炔的Pauson-Khand反应(PKR)来构建双环[5.3.0] deca-1,7-dien-9-一环系统。铑催化PKR的上证明1,2- nonadien -8-炔衍生物的实例19调查是:(i)可接受的产率可通过一致的铑催化剂的适当选择来实现([的RhCl(CO)(2)] (2)或[RhCl(CO)dppp](2))取决于起始烯丙炔,并且(ii)在该铑催化的PKR中可以耐受酯官能团以及羟基和甲硅烷氧基。
