Notes:
A new azaanthracene alkaloid, namely 9,10-dimethoxy-4-methyl-1,2-dihydro-1-azaanthracen-2-one (kalasinamide), C16H15NO3, has been isolated from the stems of Polyalthia suberosa collected in the northeastern part of Thailand. Each of the aromatic rings in the molecule is planar within \pm0.021 (2) Å. Molecules are linked to form centrosymmetric dimers by N—H...O hydrogen bonds [N...O 2.941 (4) Å].
