Three component synthesis of some gamma-spiroiminolactones under microwave-assisted solvent-free conditions

摘要

Series of some y-spiroiminolactone derivatives were synthesized through microwave-assisted,three component reaction of isocyanides,dialkyl acetylenedicarboxylates and indenoquinoxalin-11 -ones in DMF or in a solvent-less operation on solid support montmorillonite K10.
