Mild and efficient ammonium chloride catalyzed Greener synthesis of tetrahydro-β-carboline
This protocol involves the NH4Cl catalyzed Pictet−Spengler reactions of tryptamine and arylaldehydes in anhydrous MeOH solvent to gives corresponding tetrahydro-β-carbolines (THβC) with 90% yield. This methodology offers mild, efficient and green reagent
