Conclusions 1. α-Nitro-β-dimethylaminoacrolein and the dimethylammonium salt of nitromalonaldehyde are readily interconvertible. 2. Condensation of α-nitro-β-dimethylaminoacrolein with dimedone in the presence of triethylamine is accompanied by deformylation with the formation of the dimethylammonium salt of nitroethylidenedimedone. 3. Condensation of α-nitro-β-dimethylaminoacrolein with ethyl acetoacetate in the presence of triethylamine, TEBA, or alumina gives methyl o-dimethylamino-m-nitrobenzoate together with the nitroethylidene derivative of ethyl acetoacetate, β-dimethylaminocrotonic ester, and 2-nitro-4-methoxy-carbonyl-5-dimethylaminohexa-2,4-dienal.
