Abstract:
Heteropoly acids were used as catalysts for cyclodehydration of various 1, n -diols. Cyclodehydration of butane-1,4-diol, pentane-1,5-diol and hexane-1,6-diol catalysed by H 3 PW 12 O 40 gave tetrahydrofuran, tetrahydropyran and oxepane, respectively. Cyclodehydration of diethylene glycol, triethylene glycol, diethylene glycol monomethyl ether and polyethylene glycol 200 catalysed by H 3 PW 12 O 40 gave 1,4-dioxane. In particular, cyclodehydration of hexane-1,6-diol gave an excellent yield of oxepane (80%). The selectivity exhibited by the H 3 PW 12 O 40 catalyst was even better than that exhibited by other reported catalyst systems for similar cyclodehydration reactions.

Abstract:
Cyclodehydration of Diols in Acidic Ionic Liquids In the presence of sulfonic acid group functionalized Bronsted-acidic ionic liquids, cyclodehydration of 1,2-ethanediol and 1,4-butanediol is investigated. The role of structure and catalytic activity of ionic liquids on the formation of cyclic ethers: 1,4-dioxane and tetrahydrofuran - is determined.

Abstract:
The sequential N-functionalization of 2-aminobenzylamine (2-ABA) followed by cyclodehydration allowed for a straightforward and efficient synthesis of 3,4-dihydroquinazolines with N-aryl substituents bearing electron-withdrawing groups. The sequence involves an initial SNAr displacement, N-acylation and MW-assisted ring closure. Remarkably, the uncatalyzed N-arylation of 2-ABA led to the monosubstitution product using equimolar amounts of both reagents. The individual steps were optimized achieving good to excellent overall yields of the desired heterocycles, avoiding additional protection and deprotection steps. A mechanistic interpretation for the cyclodehydration reaction promoted by trimethylsilyl polyphosphate (PPSE) is also proposed on the basis of literature data and our experimental observations.

Abstract:
Des derives phosphonoindoliques sont prepares par cyclisation d'arylhydrazones d'oxoalkylphosphonates selon fisher et par cyclodeshydratation d'arylamino-1 et arylamino-3 oxo-2 propylphosphonates selon bischler. Des indolyl-2 et indolyl-3 phosphonates, des indolylmethyl-2 et des indolylmethyl-3 phosphonates diversement substitues et leurs acides phosphoniques correspondants sont decrits. Toutes structures sont analysees par rmn **(1)h, **(31)p et 1**(3)c. L'analogue phosphore de l'intermediaire a aussi ete prepare. L'extention de la reaction de bischler aux aryloxycetones permet d'atteindre des benzofuryl-2 phosphonate et de benzofurylmethyl-3 phosphonates. Deux nouveaux reactifs sont utilises pour acceder aux arylaminocetones et aux aryloxycetones : les chloro-1 et chloro-3 methoxycarbonylhydrazono-2 propyl-phosphonates de diethyle, composes qui, traites en milieu basique, donnent des azoenes qui additionnent les anilines et les phenols. Ces azoenes additionnent aussi les carbanions, notamment les carbanions derives de cetones pour conduire, apres hydrolyse soit a des derives du pyrrole, soit a des dioxy-2, -5-alkylphosphonates precurseurs de cyclopentenones selon wittig-horner
