[EN] SUBSTITUTED TETRAHYDROISOQUINOLINE COMPOUNDS AS FACTOR XIA INHIBITORS [FR] COMPOSÉS TÉTRAHYDROISOQUINOLINES SUBSTITUÉS EN TANT QU'INHIBITEURS DU FACTEUR XIA
An approach to 3-bromo-4-alkyl-6-aryl-5,6-dihydropyridin-2-ones and 3 -bromo-5-ethyl-6-aryl-5,6-dihydropyridin-2-ones starting from beta,gamma-unsaturated alpha-bromoketenes and imines is reported. The presence of a bromine atom on the double bond allows performing aziridination or bromine displacement with an amine. The reaction gave fused bicyclic N-allyl-aziridines or 3-amino-substituted 5,6-dihydropyridin-2-ones, depending on the substituents on the six-membered ring. (C) 2004 Published by Elsevier Ltd.

Electroreductive Intramolecular Coupling of Aromatic β- and γ-Imino Esters: A New Synthetic Method for <i>N</i>-Alkoxycarbonyl-2-aryl-3-ones and <i>cis</i>-2-Aryl-3-ols of Pyrrolidines and Piperidines
the resulting five- and six-membered cyclized amines gave mixed ketals of N-alkoxycarbonyl-2-arylpyrrolidin-3-ones and 2-arylpiperidin-3-ones, respectively. The best result of the electroreductive intramolecular coupling was achieved using Bu4NClO4 as a supporting electrolyte and a Pb cathode in THF. Acid hydrolysis of the mixed ketals afforded N-alkoxycarbonyl-2-arylpyrrolidin-3-ones and 2-arylpiperidin-3-ones
