Abstract Aromatic aldehydes (1 a-g) yield linear condensation products (3 a-1) with dimeric ethyl and methyl cyanoacetate, resp., and dimeric malonitrile. Reduction of the condensation product of o-nitrobenzaldehyde with dimeric methyl cyanoacetate leads to methyl (3-methoxycarbonyl-1,2-dihydro-2-chinolinylidene)-cyanoacetate (4), with o-aminobenzaldehyde a carbostyril derivative5 a is obtained. In the presence of ammonium acetate aromatic aldehydes react with dimeric methyl and ethyl cyanoacetate, resp. to hexahydro-pyrimidinylidene cyanoacetates (8).
