Abstract

Fused pyridine derivativesFused pyridine derivatives R 0450 Improved Synthesis of N-Substituted 2,3-Pyridinedicarboximides with Microwave Irradiation. -Eleven 2,3-pyridinedicarboximides (IV) are prepared starting from quinolinic acid (I) or its corresponding anhydride (V). The use of microwaves results in considerably shorter reaction times and improved yields compared to conventional heating. -(BLANCO, M. M.; LEVIN, G. J.; SCHAPIRA, C. B.; PERILLO*, I.
