Abstract

3,4,5,6-Tetrahydro-7-hydroxy-2-(1,3-dithian-2-yl)- 9-alkyl-2,6-methano-2H-1-benzoxocin derivatives are readily prepared by boron trifluoride etherate-catalyzed formation of 5-alkylresorcinols with 1-thioxolanyl-2-cyclohexenol. The yieldis the highest with 5-(1,1-dimethylheptyl)resorcinol. The one with 5-pentylresorcinol is higher than with 5-methylresordnol and resorcinol apparently because of steric effects. The yields of the product increase; 3a(7%), 3b(22%), 3c(38%) and 3d(50%).
