The reaction of alkyl isocyanides with dimethyl 1,3-acetonedicarboxylate in the presence of dialkyl acetylenedicarboxylates in CH2Cl2 at ambient temperature leads to highly functionalized 2-amino-4H-pyrans and 1,2-dialkyl 4,6-dimethyl-(1E, 3E)-3 (alkylamino)-5-oxo-1,3-hexadiene- 1,2,4,6-tetracarboxylates.
