Synthesis of Ethylenetetracarboxylic Acid Derivatives
摘要:
The three-component reaction of the zwitterions generated from dialkyl acetylenedicarboxylate and isocyanides with isocyanates is described. The reaction afforded the corresponding special type of ethylenetetracarboxylic acid derivatives in good yields.
