The stem bark of Glycosmis mauritiana contained the acridone alkaloids noracronycine and des-N- methylacronycine, and two new carbazole alkaloids, 3,3,10-trimethyl-3,7-dihydropyrano[2,3-c] carbazole (glycomaurin) and 6-methyl-4-(3′-methylbut-2′-enyl)carbazol-3-ol (glycomaurrol), whose structures were confirmed by synthesis and by cyclization to dihydroglycomaurin respectively. Glycomaurin has a ring system which has not been previously found in nature.

Acridone Alkaloid

A new acridone alkaloid, citropsine A (1), and thirteen known compounds (2 - 14) were isolated from the MeOH extract of the stem bark of Citropsis articulata. Structures of all compounds were determined by detailed analyses of their 1D and 2D NMR spectra, mass spectrometric data and by comparison with previously known analogs.

The title compound, C24H31NO3{systematic name: (E)-3-[(1R*,2S*,4aS*,8aR*)-2-(benzo[d][1,3]dioxol-5-yl)-1,2,4a,5,6,7,8,8a-octahydronaphthalen-1-yl]-N-isobutylacrylamide}, is a natural product isolated from the stem bark ofB. obscura. It is composed of an octahydronaphthalene ring system substituted with an essentially planar benzodioxole ring system [r.m.s. deviation = 0.012 Å] and an extended isobutylacrylamide group. In the crystal, molecules are linked by N—H...O hydrogen bonds, forming chains propagating along [100]. The chains are linked by pairs of C—H...O hydrogen bonds, involving inversion-related benzodioxole ring systems, forming ribbons lying parallel to (010). There are also C—H...π interactions present within the ribbons.
