title: Chemical constituents of Malagasy liverworts: cyclomyltaylanoids from Bazzania madagassa.
abstract: Five cyclomyltaylanoids (2-6), together with 1R,5R-diacetoxycyclomyltaylan-10-one (1), (+)-globulol, and ent-4beta,10alpha-dihydroxyaromadendrane have been isolated from the diethyl ether fraction of the Malagasy liverwort, Bazzania madagassa. The structure of 1 was confirmed by X-ray analysis, while those of the compounds were established on the basis of one- and two-dimensional NMR spectroscopic evidence, and comparison with data reported in the literature. The chemosystematics of B. madagassa are discussed.
