A novel and unexpected reaction of 2-alkynylbenzaldoximes with ketenes in the presence of silver triflate (10 mol%) under mild conditions is discovered. This reaction proceeds through 6-endo-cyclization, [3 + 2] cycloaddition, and rearrangement, leading to isoquinoline derivatives in moderate to good yields.
