DEFINITION

Classification: 514/192

1-thia-4-aza-bicyclo (3.2.0.) heptane ring containing (including dehydrogenated) e.g., penicillins, etc.):

(under subclass 183) Subject matter wherein the heterocyclic compound contains a 1-thia- 4- aza-bicyclo (3.2.0) heptane ring system having the following structure, and may contain a double bond between ring members, e.g., penicillins, etc. [figure]

(1) Note. The Ring Index uses a different system for numbering the ring members. However, in the indents hereunder which refer to positions, the numbers shown in the definition are employed.

(2) Note. Patents reciting broadly "penicillins," "penicillin type," or "penicillin drugs" are placed herein.
