✦ Synopsis

An unexpected four-component (3+1) reaction of an alkyl isocyanide with alkylidene-substituted Meldrum's acid in CH 2 Cl 2 at room temperature produces imino-furopyranones in good yields. The structures of the products are deduced from their IR, 1 H NMR, and 13 C NMR spectra and by X-ray analysis. The products are structurally similar to 2H-furo[2,3-c]pyran-2-one natural products.
