Ring Opening/Site Selective Cleavage in N-Acyl Glutarimide to Synthesize Primary Amides

A LiOH-promoted hydrolysis selective C-N cleavage of twisted N-acyl glutarimide for the synthesis of primary amides under mild conditions has been developed. The reaction is triggered by a ring opening of glutarimide followed by C-N cleavage to afford primary amides using 2 equiv of LiOH as the base at room temperature. The efficacy of the reactions was considered and administrated for various aryl and alkyl substituents in good yield with high selectivity. Moreover, gram-scale synthesis of primary amides using a continuous flow method was achieved. It is noted that our new methodology can apply under both batch and flow conditions for synthetic and industrial applications.

A Convenient Palladium-Catalyzed Aminocarbonylation of Aryl Iodides to Primary Amides under Gas-Free Conditions

A convenient procedure for the synthesis of aromatic primary amides through palladium-catalyzed aminocarbonylation of aryl iodides has been developed. With ammonium hydrogen carbonate as the solid nitrogen source and formic acid as the liquid CO source, a variety of primary amides were obtained in moderate to excellent yields under gas-free conditions.

TBAI-catalyzed oxidative synthesis of benzamides from acetophenones and carbinols

An interesting and convenient procedure for the oxidative transformation of acetophenones and carbinols to primary benzamides has been developed. By using tetra-n-butylammonium iodide (TBAI) as the catalyst and tert-butyl hydroperoxide (TBHP) as the oxidant, the desired benzamides were isolated in moderate to good yields in aqueous solution. Notably, not only acetophenones but also propiophenones can be applied as substrates as well. Hence, we believe that this new procedure is not just a catalytic version of the iodine-based method. the Partner Organisations 2014.
