Alkyl Isocyanides Promoted Synthesis of Functionalized Azadienes from Dialkyl Acetylene Dicarboxylates and N-Hydroxysuccinimide

The reaction between N-Hydroxy succinimide with dialkyl acetylene dicarboxylates in the presence of isocyanides, leads to functionalized azadienes in good yields. The product were analized and the structures of reaction compounds were deduced from their IR, 1HNMR and 13CNMR spectra.
