Onion extract catalyzed novel synthesis of pyrazine

An efficient catalytic system for analyzing Pyrazine derivatives using an extract of onion at room temperature is discussed in this research study. A very good to excellent yields in reasonably short reaction time, high atom economy, usage of readily available starting material, operational simplicity and easy workup are the fundamental features of this protocol. The versatility our method is determined by synthesizing a large number of pyrazine derivatives with (85-96%) good yield.
