One-Pot Three-Component Synthesis of Stable Pyrrole-3-Selones Using Propargyl Amines, Acyl Chlorides, and Elemental Selenium

Stable pyrrole-tailored selones, 1,2,5-trisubstituted-1,2-dihydro-3Н-pyrrole-3-selones, have been synthesized in 69–75% yields from aminoacetylenic ketones, 4-aryl(hetaryl)-3-alkylarylhetaryl-1-butynes, and elemental selenium (KOH/EtOH, room temperature, 10 h). The same compounds can be synthesized in one-pot...
