Transition metal-free and temperature dependent one-pot access to phenanthrene-fused heterocycles via a 1,3-dipolar cycloaddition pathway

Abstract

A versatile, operationally simple, temperature-dependent, and transition metal-free one-pot protocol has been devised for the preparation of novel phenanthrene-fused pyrazoles. Notably, the overall process involved an intermolecular condensation, an intramolecular...
