文摘

An excellent catalyst DABCO has been found to catalyze C-C bond formation reaction between activated methylenes and alkynes. The transformation has provided a facile route for the synthesis of 2H-pyran-2-ones or unsaturated alkenoic acid ester derivatives and explored the new possibilities of N-catalysts for Michael addition of nucleophiles with alkynoates.
