摘要

Pyrolysis of the aminomethylene Meldrum's acid derivatives (5-aminomethylene-2, 2- dimethyl-1, 3-dioxane-4, 6-dione)(),(),(), and () causes hydrogen transfer reactions which result in specific functionalisation of the amino substituent: tertiary amino substrates give 1, 2- dihydropyrrol-3-ones (60%) by ring closure, wh
