Efficient one-pot synthesis of hydroxyflavanones by cyclization and O-demethylation of methoxychalcones

Liu, Tao,Ying, Huazhou,Lin, Guan,Hu, Yongzhou

, p. 1815 - 1821 (2008/12/20)

An efficient one-pot method for the synthesis of hydroxyflavanones is described. Methoxychalcones are treated with 36% HBr to afford cyclization and regioselective O-demethylation products (2a-i) while cyclization and complete O-demethylation products (3a
