A highly stereoselective Rh(I)-catalyzed 1,3-acetoxyl rearrangement of 1,2-allen-3-yl carboxylates leading to 2-acetoxy-1,3(E)-alkadienes has been developed. In addition to the high catalytic efficiency and the scope, the excellent E-selectivity of the double bond is remarkable.
已开发出高度立体选择性的Rh(I)催化的1,2-烯丙基-3-基羧酸酯的1,3-乙酰氧基重排,产生2-乙酰氧基-1,3(E)-链二烯。除了高催化效率和适用范围外,双键极好的E选择性也很显着。
