摘要：

Although 4-alkyl- and 4-aryl-3,5-pyridinedicarboxylates are well-known,1 the corresponding 2,4-dialkoxy analogues have not been reported. In a continuing effort to synthesize 2-(trifluoromethyl)-3,5-pyridinedicarboxylates as herbicides,2,3 we decided to prepare 2,4-dialkoxy-6- (trifluoromethyl)-3,5-pyridinedicarboxylates to study. © 1990, American Chemical Society.
