3-COUMARANONE Chemical Properties,Usage,Production

Chemical Properties

white to light yellow crystal powde

Uses

3-Coumaranone is used in the aurones, [2-benzylidenebenzofuran-3(2H)-ones] by reacting with appropriate aldehyde. It is involved in the condensation reaction with aldehydes in the presence of morpholine acetate to prepare substituted 2-(arylidene)benzofuran-3(ZH)-ones. In Horner-Wadsworth-Emmons reaction, it reacts with diethyl? cyanomethyl?phosphonate to give 3-(cyanomethyl)benzofurans, which is an intermediate in the synthesis of antihyperglycemic agents.

General Description

Benzofuran-3(2H)-one undergoes condensation with aldehydes in the presence of morpholine acetate to yield substituted 2-(arylidene)benzofuran-3(ZH)-ones. It undergoes acid- or base-catalyzed condensation with an appropriate aldehyde to yield aurones [2-benzylidenebenzofuran-3(2H)-ones].
