A NEW SYNTHESIS OF HOMOISOFLAVANONES (3-BENZYL-4-CHROMANONES)
Jain, Amolak C.,Mehta, Anita
, p. 5933 - 5938 (2007/10/02)
Two 7-hydroxyhomoisoflavanones (6a/6b) have been synthesized from corresponding 2'-hydroxydihydrochalcones (2a/2b) in about 33percent overall yields.The stages are : (i) selective protection of C4'-hydroxyl in 2a/2b with EtO.CH2Cl (1 molar equiv.) in the
