2-(Un)substituted-2′-methoxy-7-hydroxyisoflavones were synthesized. They were derivatized at the phenol hydroxyl using alkylation and acylation reactions and Mannich base formation.

Recyclization of the chromone ring in several natural isoflavonoids and their analogs by reaction with hydroxylamine was studied. It has been found that the most suitable base for carrying out the reaction is N-methylmorpholine. Several derivatives of 4-aryl-5-(2-hydroxyphenyl)isoxazole were synthesized.
