L. Jukic et al., A synthesis and transformations of alkyl 2-[2-cyano-2-(2-pyridinyl)ethenyl]amino-3-dimethylaminopropenoates. A one-pot synthesis of pyrrolo[3,2-d]pyrimidin-4-ones, HETEROCYCLE, 53(4), 2000, pp. 805-820
Alkyl 2-[2-cyano-2-(2-pyridinyl)ethenyl]amino-3-dimethylaminopropenoates (8
) and (9) were transformed by heating into alkyl 2-[2-cyano-2-(2-pyridinyl)
ethenyl]amino-3-[2-methoxycabonyl-4-(2-pyridinyl)-1H-pyrrol-3-yl]aminoprope
noates (12) and (13). Compounds (8) and (9) can be transformed in the prese
nce of primary aliphatic amines into substituted pyrrolo[3,2-d]pyrimidines
(17-19).
