摘要：

The title one-pot reaction occurs through a sequence of [2+2] cycloaddition ring opening to dienamines and formation of a 1,5-dipole by [1,6] hydrogen-shift. This intermediate may cyclize or in sterically suitable cases and at lower temperatures, lead to isolable N-vinyl enamines by proton transfer.
