A catalytic synthesis of carboniolamide has been reported. The strategy was straightforward with aldehyde and amide as starting materials. The products can be isolated as precipitates from the reaction mixture. The factor that stabilizes the labile functionality of hemiaminal was elucidated as a sp(3) hybridized oxygen.
