Popis: 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.
