Treatment of the disulfide (90) with iodine in dioxane under various conditions gives low yields of 5,6-dimethoxy-2,3-dihydrobenzo[6]-thiophene.346 At high temperatures in ethylene glycol a mixture of this compound and the dehydrogenated product, 5,6-dim ethoxy-benzo[6]thiophene, is obtained. These observations demonstrate the importance of the double bond in the side chain of the mercapto-acrylic acids (88) in promoting their cyclization. [Pg.234]
