Abstract

A highly efficient method for the synthesis of spiropyrazolone derivatives with structural diversity has been established via a facile three-component 1,3-dipolar cycloaddition of aldehydes, amino ester, and unsaturated pyrazolones. This protocol is applicable to a variety of unsaturated pyrazolones and aldehyde-derived azomethine ylides, providing an easy access to spiropyrazolone-based tetrahydro­pyrroles with structural diversity in high yields (up to 97%).
