thermal rearrangement of tertiary and secondary enamino carboxamides has been developed. The enamine group of an enamino carboxamide, in which no electron-withdrawing group is present in the enophile, can be involved in the ene reaction and the enamino carboxamide can be transformed into enamino or imino spirolactams. In the case of secondary carboxamido enamines, the diastereoselectivity is higher than 98%

Treatment of N,N-diallyl and N-alkyl, N-propargyl-β-ketoamides with NaH and then with N-iodosuccinimide led to the formation of iodomethyl- and iodomethylene-β-ketolactams.
