Organolead-mediated Arylation of Allyl β-Ketoesters: A Selective Synthesis of Isoflavanones and Isoflavones
Donnelly, Dervilla M.,Finet, Jean-Pierre,Rattigan, Bernard A.
, p. 1729 - 1736 (2007/10/02)
Arylation of A-ring substituted and unsabstituted 3-allyloxycarbonylchroman-4-ones with aryllead(IV) triacetates followed by selective catalytic deallyloxycarbonylation affords isoflavanones or isoflavones in high overall yields.The highest yield in the arylation step was observed in the reaction of 5,7-dimethoxychroman-4-one with the more hindered 2,4,6-trimethoxyphenyllead triacetate.

A new general synthesis of hydroxy- (5e-h) and methoxy- (5e-d) isoflavones has been accomplished in overall yields of 47-73percent from the corresponding 2-hydroxydeoxybenzoins (1a-h).The first step involves reaction with appropriate amounts of ethoxymeth
SYNTHESIS OF METHOXYISOFLAVONONES FROM ARYLMETHYL o-HYDROXYARYL AND PARAFORMALDEHYDE
Pinkey,Jain, Pramod K.,Grover, Surinder K.
, p. 355 - 358 (2007/10/02)
Paraformaldehyde reacts with benzyl o-hydroxyphenyl ketones in the presence of diethylamine in methanolic solution to afford isoflavanones in excellent yields.
