DEFINITION

Classification: 548/207

(under subclass 206) Compounds wherein the thiazole ring is a cyclo in a polycyclo ring system.

(1) Note. A thiazole ring in a polycyclo ring system is numbered as if it were a single ring and not part of a ring system; accordingly, the thiazole ring in each of the following poly-cyclo ring systems is considered to be 1, 2-thiazole: [figure] [figure]
