SYNTHESIS AND PROPERTIES OF 4- AND 4,5-SUBSTITUTED 2,7-DI-tert-BUTYLTHIEPINS
Various 4- and 4,5-substituted 2,7-di-tert-butylthiepins such as 4-ethoxycarbonyl-(6), 4-formyl- (7), 4-hydroxymethyl- (8), 4-methyl- (12), 4-methy1-5-hydroxymethy1-(13), and 4,5-dimethyl derivatives (16), and so on, were synthesized by functional group transformation and some of their properties were examined.
