The Definite Structure of Americanin-A and Hydnocarpin
By comparison of degradation products of rac-americanin-A dimethyl ether (2) with synthetic precursors of silybin (11) and isosylibin (20), respectively, the definite structure of americanin-A (1) was established.A flavonolignan derivative synthesized als

Benzodioxans by Oxidative Phenol Coupling. Synthesis of Silybin
Oxidative coupling of substituted catechols with isoeugenol or coniferyl alcohol in the presence of silver oxide affords 2,3-trans-1,4-benzodioxans in good yield.The reaction is highly regioselective when the catechol bears an alkyl substituent, much less
