An Efficient Synthesis of Trialkyl N-Alkyl-6-methyl-2-pyridone-3,4,5-tricarboxylates
摘要:
An efficient synthesis of trialkyl N-alkyl-6-methyl-2-pyridone-3,4,5-tricarboxylates from three-component reaction of the zwitterions generated from dialkyl acetylenedicarboxylates and alkyl isocyanides with alkyl 2-chloroacetoacetates is described.
