Isocyanide-based three-component synthesis of functionalized 5-alkylimino-2,5-dihydrofuran-3,4-dicarboxylate and their conversion to substituted furanones

The zwitterionic 1:1 intermediates formed from alkyl isocyanides and acetylenic esters are trapped by alkyl bromides to form 5-alkylimino-2,5- dihydrofuran-3,4-dicarboxylate in relatively good yields at room temperature under solventless conditions. Hydro
