Abstract Reactions of aminals of conjugated ω-dimethylaminoaldehydes with Meldrum's acid,N,N′-(o-phenylene)malonamides, and 2,3-dihydrophenalene-1,3-dione afford δ-dimethylaminodienones, substituted 2-dimethylamino-2H-pyrans, or oxanine salts. Cation-anionic polymethine dyes have been obtained from the latter.
