Stereoselective Aminomethylation of m-Cresol with Chiral Amine Mediated by 4 A0 Molecular Sieves Under Neat Conditions

Abstract

A minomethylation at ortho position with respect to hydroxyl group of mcresol in presence carefully dried 4A molecular sieves under neat conditions. One pot, two component,Mannich reaction of m-cresol with imine at 600C temperature under solvent free conditions affords the corresponding aminomethylated products in good yields, with moderate stereoselectivity.
