An improved microwave assisted one-pot method for the synthesis of twelve new aryldiazenylchromeno [4,3-b] pyrrolidines via intramolecular azomethine ylide cycloaddition route is described. The method is efficient and advantageous over conventional and solvent-free thermal methods. The stereochemistry of the compounds was confirmed on the basis of various NMR experiments, and finally by single crystal
描述了一种改进的微波辅助一锅法,该方法通过分子内偶氮甲碱内酯环加成路线合成了十二种新的芳基二氮烯基壬二烯基[4,3- b ]吡咯烷。该方法比常规的和无溶剂的热方法有效且有利。基于各种NMR实验,并最终通过单晶X射线衍射数据,证实了化合物的立体化学。基于N-甲基或乙基吡咯烷的杂环具有良好的生物学活性。
