DEFINITION

Classification: 514/230.8

Chalcogen bonded directly to ring carbon of 1, 4-oxazine ring:

(under subclass 228.8) Subject matter in which the six-membered hetero ring has the following basic structure which may contain double bonds between ring members, as illustrated below, and in which chalcogen (i.e., oxygen, sulfur, selenium, or tellurium) is bonded directly to a ring carbon of the six-membered hetero ring.
