Arylmethylene-3H-furan(pyrrol)-2-ones in reactions of [3+2]-cycloaddition with activated hydrazones
摘要:
Spiropyrrolidine derivatives were synthesized for the first time by [3+2]-cycloaddition of 3-arylmethylene-3H-furan(pyrrol)-2-ones to N-benzylidenebenzylamine activated by the system AcOAg-Et3N. The reaction route and the spectral characteristics of the first obtained compounds have been discussed.
