Abstract
8-Hydrox-5:7-dimethoxy-4-(p-methoxyphenyl) coumarin has been synthesized by condensing 1,2-dihydroxy-3,5-dimethoxybenzene with p-methoxybenzoylacetic ester. The m.p. of the synthetic compound and its acetate differ from the reported m.p. of exostemin and its acetate but there is general agreement in spectral data. The simpler 4-phenyl analogue has also been synthesized. The m.ps of the simpler analogue, its methyl ether and acetate are remarkably close to those of exostemin and its derivatives indicating the possibility of some error in the study of the natural product.
