Mesoporous silica nanoparticles (MSNs) as an efficient and reusable nanocatalyst for synthesis of β-amino ketones through one-pot three-component Mannich reactions

摘要

Mesoporous silica nanoparticles (MSNs) proved efficient and reusable in the catalytic synthesis of β-amino ketones, through three-component Mannich reaction of ketones, aromatic aldehydes and aromatic amines under solvent-free conditions. Simple reaction conditions coupled with simple work-ups, makes this methodology a superior option for the synthesis of such β-amino ketones.
