Three-Component Reaction between alkyl(aryl) Isocyanides and Dialkyl Acetylenedicarboxylates in the Presence of Ethyl Trifluoroacetate

Three-Component Reaction between alkyl(aryl) Isocyanides and Dialkyl Acetylenedicarboxylates in the Presence of Ethyl Trifluoroacetate

The 1:1 intermediate generated by the addition of alkyl(aryl) isocyanides to dialkyl acetylenedicarboxylates is trapped by ethyl trifluoroacetate in the absence of a catalyst to form highly functionalized dialkyl 5-[alkyl(aryl)imino]-2-ethoxy-2-(trifluoromethyl)-2,5-dihydrofuran–-3,4-dicarboxylates...

Zusammenfassung:The 1:1 intermediate generated by the addition of alkyl(aryl) isocyanides to dialkyl acetylenedicarboxylates is trapped by ethyl trifluoroacetate in the absence of a catalyst to form highly functionalized dialkyl 5-[alkyl(aryl)imino]-2-ethoxy-2-(trifluoromethyl)-2,5-dihydrofuran–-3,4-dicarboxylates in good yields.
