Article abstract of DOI:10.1055/s-1988-27483

Rearrangement of 2,4-dinitro-, and 2,4,6-trinitrobenzylidenemalonates in reactions with primary, secondary and tertiary amines, both in the presence and in the absence of alcohols to give 2-amino-4-nitro-, and 2-amino-4,6-dinitrobenzoic acid derivatives is described.Depending on the reaction conditions, various rearrangement products, e.g. ester, ether, amide, are obtained selectively.
