Abstract

2-Alkyl-4H-benzo [1, 4] thiazine-3-one derivatives have attracted much interest due to their biological functions [1]. For example, they can be used as effective tranquilizers [1b], angiotensin converting enzyme inhibitors [1c], or aldose reductase inhibitors [1d], and some [1, 4] benzothiazines show anticancer activities [2]. These compounds are also attractive targets for library development because their structure contains multiple positions for facile ...
