Thiazine

Thiazines are heterocyclic organic compounds having a ring of four carbon, a nitrogen and a sulfur atom. Due to the different arrangement of the nitrogen with respect to the sulfur atom not only includes the most common basic structure of 1,4- thiazine, and derivatives derived from 1,2- thiazine and 1,3- thiazine. The Thiazines be used as a basic structure for dyes, sedatives and insecticides, the phenothiazines derived from 1,4- thiazine represent (eg methylene blue as a representative of thiazine dyes ), the most common derivatives. Important representatives of the 1,3- thiazine derivatives are, for example, cephalosporins, which are used as the antibiotics, and Xylazine. 1,2- thiazine derivatives (eg, partially hydrogenated ) are obtained by [ 4 2 ] cycloaddition.

The simplest is the thiazine 1,4- thiazine C4H5NS itself In contrast, the compound does not contain thiomorpholine C4H9NS double bonds in the ring.
