Cycloaddition of 4,5-Dihydrooxazol-5-one Derivatives to 4-Methylbenzene-1,2-dithiol

Reactions of 4,5-dihydrooxazol-5-one derivatives with 4-methylbenzene-1,2-dithiol in the presence of triethylamine includes nucleophilic attack by the thiol group on the carbonyl carbon atom in the oxazole ring, followed by opening of the latter and recyclization to 1,4-benzodithiine derivatives.__________From Zhurnal Organicheskoi Khimii, Vol. 41, No. 7, 2005, pp. 1067–1070.Original English Text Copyright © 2005 by Tikdari, Fozooni, Vazee, Hamidian.The original article was submitted in English.
