  1,4-Dihydropyridines bearing carbonyl functions in the 3- and 5-positions, being optionally substituted by lower alkyl in the 6-position, being substituted in the 4-position by lower alkyl, phenyl, substituted phenyl or a heterocyclic group, and being fused through the 1- and 2-positions to a five, six or seven membered cycloalkyl ring, one methylene group of which can be replaced by sulfur, oxygen imino or alkylimino, are antihypertensive agents and coronary vessel dilators. The compounds, of which 6-methyl-4-(3-nitrophenyl)-1,2-pentamethylene-1,4-dihydropyridine-3,5-dica rboxylic acid 3,5-diethyl ester is a representative embodiment, are prepared through condensation of an ylideneacetoacetic acid ester and a cyclic enamino carbonyl derivative.

  The domino aza-annulation of cyclic enaminones with maleic anhydride and maleimides was investigated, and selectively one-step skeletally diverse synthesis of each alkaloid-like pyrrolizidinone, indolizidinone, and pyrrolo[1,2-a]azepinone was developed, switching between aza-[3+3] and aza-[3+2] modes of formal cycloaddition reactions. For the synthesis of pyrroloazepinones, seven-membered enaminone and maleic anhydride or maleimides are efficient, via the [3+2] mode. To access indolizidinones, five or six-membered enaminones are the choice, and both [3+2] and [3+3] modes were viable exclusively with maleic anhydride. Pyrrolizidinone can be selectively synthesized in good yield through the [3+2] mode, only with five-membered enaminone and N-(4-NO2Ph)maleimide, under catalysis by PTSA. (C) 2013 Elsevier Ltd.
