Abstract

CE PROCEDE CONCERNE LA CYCLISATION D'ESTER DE L'ACIDE CHLOROCARBOXYLIQUE DE FORMULE GENERALE: (CF DESSIN DANS BOPI) DANS LAQUELLE R, R, R, R, R ET R SONT IDENTIQUES OU DIFFERENTS ET REPRESENTENT UN RADICAL ALKYLE LINEAIRE OU RAMIFIE EN C A C, OU DANS LAQUELLE ILS PEUVENT EGALEMENT, A L'EXCEPTION DE R, REPRESENTER UN ATOME D'HYDROGENE, CETTE CYCLISATION DEVANT FOURNIR DES ACIDES CYCLOPROPANECARBOXYLIQUES, EVENTUELLEMENT SUBSTITUES, ET LEURS ESTERS, DE FORMULE GENERALE: (CF DESSIN DANS BOPI) DANS LAQUELLE LES SYMBOLES R A R ONT LA SIGNIFICATION DONNEE CI-DESSUS ET DANS LAQUELLE R PEUT EN OUTRE REPRESENTER UN ATOME D'HYDROGENE, LA CYCLISATION S'EFFECTUANT AU MOYEN D'UN AGENT DE CONDENSATION BASIQUE ET ETANT EVENTUELLEMENT SUIVIE D'UNE SAPONIFICATION DE L'ESTER. IL EST CARACTERISE EN CE QU'ON UTILISE, COMME AGENT DE CONDENSATION, UN ALCOOLATE ALCALIN ANHYDRE, EN CE QUE LA CYCLISATION S'EFFECTUE DANS UN SOLVANT ORGANIQUE INERTE ET EN CE QU'ON ELIMINE PAR DISTILLATION EN CONTINU L'ALCOOL QUI SE FORME LORS DE LA REACTION.
