C-C Bond Cleavage-Induced C- to N-Acyl Transfer for Synthesis of Amides. | LitMetric

C-C Bond Cleavage-Induced C- to N-Acyl Transfer for Synthesis of Amides.

Org Lett

Department of Chemistry, Yeungnam University, 280 Daehak-Ro, Gyeongsan, Gyeongbuk 38541, Republic of Korea.

Published: May 2024

A new approach for the preparation of amides was developed using C-C bond cleavage that initiates C- to N-acyl transfer, employing activated ketones as acylation reagents and amine nucleophiles. The reaction was operational under the coupling reagent system that is commonly utilized for peptide bond formations. The method enables practical preparation of amides using linear and cyclic ketone substrates under mild conditions.
