DEFINITION

Classification: 546/124

Tropanes (including nor and dehydro forms):

(under subclass 112) Compounds in which the bicyclo ring system has the following basic structure: [figure]

(1) Note. Included here also are the nor- (absence of methyl group on ring nitrogen) and dehydro- (presence of double bonds between ring members) forms of tropane.
