A SIMPLE AND EFFICIENT APPROACH TO THE SYNTHESIS OF FUROPYRAN DERIVATIVES: FOUR-COMPONENT REACTION OF ISOCYANIDES WITH ARYLIDENE-SUBSTITUTED MELDRUM’S ACID

Аннотация

An four-component (3+1) reaction of an alkyl isocyanide with arylidene-substituted Meldrum's acid in CH2Cl2 at room temperature produced furo[3,4-b]pyran-5(7H)-one derivatives in good yields. The structures of the synthesized compounds were confirmed by IR, NMR spectroscopy, mass spectra, and elemental analysis.
