Corresponding dienediaminodicarbonyl compounds were synthesized by the reactions of a series of dimethylaminomethylenedicarbonyl compounds with N,N-dimethylacetamide and N-methylcaprolactam diethylacetals.In the reaction of N-methylvalerolactam diethylacetal, the process is accompanied by a rearrangement with the formation of a 3-methylenepiperidon-2-one derivative.It was found that the introduction of a substituted amino group into the meso-position of the intermediate α-alkoxyenamine (in the preparation of dienediaminodicarbonyl compounds) takes place intermolecularly, and a general scheme of the unusual reaction studied has been proposed.
