[e]thieno[2,3-b]pyridine-2-carboxylates (3a-d) gave the corresponding o-aminocarboxylic acids 4a-d. Heating the latter compounds (4a-d) with acetic anhydride furnished the oxazinone derivatives 5a-d which, in turn, underwent recyclization reaction to give the corresponding pyrimidinones 6a-d upon treatment with ammonium acetate in acetic acid. Reaction of 3-amino-4-aryl-cycloalka[e]thieno[2,3-b]py
