The formation of some pyrroles, pyrrolines, pyrrolidines, pyridines, and tetra-hydropyridines were considered above. Next come the pyrazines, a very important group of odorants. Pyrazines have been reviewed periodically by Maga.231-233 Vemin and Parkanyi216 have tabulated 26 pyrazines, as well as 11 6,7-dihydro-(5//)-cyclopentapyrazines and 9 5,6,7,8-tetrahydroquinoxalines from 15 systems. 

A review entitled General Methods of Alkaloid Synthesis includes pyrrolidine, pyridine, and Sceletium alkaloids.1 Another summarizes nitrogen-containing compounds in tobacco and tobacco smoke, and includes some pyrroles, pyrrolidines, pyridines, and alkaloids related to nicotine.2...
