Pyrolysis of the aminomethylene Meldrum's acid derivatives (5-aminomethylene-2,2-dimethyl-1,3-dioxane-4,6-dione) (1), (7), (11), and (12) causes hydrogen transfer reactions which result in specific functionalisation of the amino substituent: tertiary amino substrates give 1,2-dihydropyrrol-3-ones (60percent) by ring closure, while secondary amino substrates give quinolin-4-ones (90percent) or enaminoenaminones (90percent).
3-Hydroxypyrroles and 1H-Pyrrol-3(2H)-ones. Part 1. Formation and X-Ray Crystal and Molecular Structure of 1-cyclohexyl-2,2-pentamethylene-1H-pyrrol-3(2H)-one

The title compound (4) is formed by flash vacuum pyrolysis of a dicyclohexylaminomethylene derivative of Meldrum's acid, (2) and its structure was determined by X-ray crystallograhy.Deuterium-labelling studies show that the reaction mechanism involves a s
