Ah. Mericli et al., ISOLATION AND STRUCTURE OF RAVEYINE, A NOVEL NORDITERPENOID ALKALOID FROM CONSOLIDA-RAVEYI (BOISS) SCHROD, Heterocycles, 45(10), 1997, pp. 1955-1965
From the aerial parts of Consolida raveyi (Boiss) Schrod., a new nordi
terpenoid alkaloid designated as raveyine has been isolated along with
the known alkaloids ajaconine, azitine, chellespontine and isoatisine
. The structure of raveyine (4) was determined on the basis of homonuc
lear H-1 decoupled C-13, DEPT, 2D H-1 phase sensitive COSY, TOCSY, ROE
SY, H-1-C-13 HMQC, HMQC-clean TOCSY and HMBC NMR spectral studies.
