A general method for the synthesis of isoflavones by oxidative rearrangement of flavanones using thallium (III) perchlorate

Oxidation of flavanones with thallium(III) perchlorate in acetonitrile or dimethoxyethane leads to 2,3-aryl migration providing a general method for the synthesis of isoflavones having electron relasing as well as electron withdrawing substituents at C2-aryl ring and the mechanism in relaltion to in vivo is discussed.

Intramolecular Ketene Cycloadditions. Synthesis of Isoflavones and 3-Aroylbenzofurans

The conversion of 2-(carboxyalkoxy)benzils to the corresponding phenoxyketenes to an intramolecular ketene cycloaddition to ultimately yield isoflavones and/or 3-aroylbenzofurans.The ketenes may be generated by the classical dehydrochlorination of the acid chloride or by using Perkin reaction conditions, sodium acetate in refluxing acetic anhydride.The initial cycloaddition products are the corresponding β-lactones, which may decarboxylate to the isolated isoflavones and/or 2-aroylbenzofurans.The product distributions are dependent upon the substitution pattern in the orginal benzil acids.
