A Concise Approach to Oxo-Dehydrorotenoid by Direct Lactonization and the Total Syntheses of Stemonone, Rotenonone, 6-Oxo-dehydroelliptone, and 6-Oxo-6a,12a-dehydrodeguelin
An approach to construct the oxo-dehydrorotenoids via direct lactonization of isoflavone-2-carboxylic acids is reported. The present reaction proceeds smoothly with good substrate scope and an operationally simple protocol. The application of this method
SYNTHESIS OF ANALOGS OF NATURAL ISOFLAVONES FROM 2,4-DIHYDROXYDEOXYBENZOINS
A number of analogs of natural isoflavones have been synthesized.The starting materials were 2,4-dihydroxydeoxybenzoins obtained under modified conditions of the Houben-Hoesch reaction.The yields of the isoflavones synthesized were 63-69percent.All the an
