4-Alkoxy-6-alkyl-2-pyrones as Precursors for 4-Alkoxy-6-alkyl-2-aminobenzoic Acid Derivatives
Tam, Tim Fat,Coles, Peter
, p. 383 - 386 (2007/10/02)
4-Alkoxy-6-alkyl-2-pyrones undergo Diels-Alder reaction with dimethyl acetylenedicarboxylate to give dimethyl 4-alkoxy-6-alkylphthalates, which can be converted into 4-alkoxy-6-alkyl-2-aminobenzoic esters via a simple two-step sequence.
