Abstract

Treatment of cyclic ketone N-tosylhydrazones with chalcones in the presence of cesium carbonate at 110 °C affords spiropyrazolines with high selectivity and excellent yields. This protocol possesses many advantages such as readily available and stable starting materials, high selectivity, operational simplicity, and catalyst-free conditions.
