G. Smith, E. Wang, J. P. Bartley and R. C. Bott

Abstract: The crystal structure determination of one of the substituted -chromene components isolated in the hexane extraction of the fruit of the indigenous Australian tree Melicope ellyrana, the methyl ether of the known compound alloevodionol, is reported. In this compound, 1-(5,7-dimethoxy-2,2-dimethyl-2H-1-benzopyran-8-yl)ethanone, C₁₅H₁₈O₄, the methoxy groups are approximately coplanar with the aromatic ring, while the acetyl group is normal to the ring.
