摘要：
The cycloaddition reaction/conjugate addition reaction is effectively controlled by a suitable combination of vinylketene dithioacetals 1(a-c) and in situ generated p-benzoquinones 2(a-c). The reaction of 1c with 2b provided cycloaddition product 3c, while the reaction of 1a with 2b yielded a conjugate addition product 4b in good yield.
