摘要

In the presence of 4 Å MS, both all-alkene [2 + 2 + 2] and [2 + 2] cyclizations of dimethyl methylenemalonate (DMM) with N-sulfonyl enamides were selectively achieved under In(OTf) ₃ and Cu(OTf) ₂ catalysis, respectively. In(OTf) ₃ -catalyzed [4 + 2] cyclization of the sulfonylamidocyclobutanes with another molecule of DMM or other electron-deficient alkenes was also reported.
