| الوصف: | 3-hydroxyisovaleraldehyde dimethyl acetal(I) is condensed in the presence of pyridine with 2,4-dihydroxy phenyl benzyl ketones (IIa, b, c, d) to give 2,2-dimethyl-6-phenylacetyl-5-hydroxychromenes (IIIa, b, c, d); these intermediates are directly converted into the corresponding angular 6", 6"-dimethylpyranoisoflavones (IVa, b, c, d) by condensation with ethylorthoformate in the presence of pyridine and piperidine. Compounds IV b and IV d are respectively identical with the natural products Calopogonium Isoflavone A and B wich we have described earlier. |
