  • A new methodology for the preparation of pyranochromenes was developed starting from substituted trihydroxybenzenes. This methodology was applied successfully to the total synthesis of biologically interesting compounds, clusiaphenone A, octandrenolone, O-methyloctandrenolone, trans-3''',4'''-dihydro- 3''',4'''-dihydroxy-O-methyloctandrenolone, trans-3'',4''-dihydro-3'',4''-dihydroxy-O-methyloctandrenolone, flemiculosin, laxichalcone, and racemic 3-deoxy-Ms-II.
