Abstract
A cheap and safe synthetic route to obtain 3-(1-carboxyalkyl)pyrido[2,3-d]pyrimidinediones (carboxyalkyl = -CHRCO2H; R = H; CH2; CH2Ph; Ph; CH2 (C3H3N2); (CH2)2CO2H; CH2CO2H) starting from 2,3-pyridinedicarboxylic acid is described. A process scheme consistent with empirical observations is proposed.
