Three new dibenzoylmethane derivatives were isolated from petrol extracts of the roots of Lonchocarpus latifolius and L. muehlbergianus. Molecular structures were determined from spectroscopic data, especially NMR techniques. An alkyl group bonded to the central carbon (C-8) of a natural dibenzoylmethane, had not been found before. Spectral data analysis suggested a preponderance of the respective diketotautomers.
An efficient route for commercially viable syntheses of furan- and thiophene-anellated β-hydroxychalcones
