2-Cyano-2-methylsparteine

Abstract

In the title compound, [7S-(7α,7aα,14α,14aα)]-dodeca-hydro-4-methyl-7,14-methano-2H,6H-dipyrido[1,2-a: 1',2'-e][1,5]diazocine-4-carbonitrile, C 17 H 27 N 3 , the two quinolizidine moieties have been found to have trans A/B and trans C/D configurations. The piperidine rings A, B, C and D assume chair, chair, boat and chair conformations, respectively. The methyl substituent has been shown to adopt an equatorial orientation, with the cyano substituent in an axial position.
