ACID-CATALYZED ISOMERIZATION OF 1-FORMYL-2,2-DIPHENYLTHIOCYCLOPROPANES TO 2,2-DIPHENYLTHIO-2,3-DIHYDROFURANS. A CONVENIENT METHOD FOR THE PRODUCTION OF SUBSTITUTED 2-PHENYLTHIOFURANS

In the presence of catalytic amounts of p-toluenesulfonic acid in methylene chloride trans-3-aryl(methyl)-2,2-phenylthio-1-formylcyclopropanes readily isomerize to the corresponding 2,2-diphenylthio-2,3-dihydrofurans.The latter are converted by the action

The reactions of the methyl ester, N,N-dimethylamide, and nitrile of gem-dichlorocyclopropanecarboxylic acid with sodium methoxide and ethoxide take place with opening of the three-membered ring and lead to the correponding derivatives of succinic acid.Methyl and ethyl 3-formyl-2-methylpropionate were obtained from 2,2-dichloro-1-formyl-3-methylcyclopropane under analogous conditions.The reaction of sodium thiophenolate with the functionally substituted gem-dichlorocyclopropanes takes place with retention of the three-membered ring and the formation of the corresponding substituted diphenyl thioacetals of cyclopropanone.
