THE well-known synthesis of polypeptides from N-carboxy-α-amino-acid anhydrides has been extensively used recently for preparative purposes, but the mechanism of the reaction has received ...
Photoactivated ketones prove to be promising H-atom transfer photocatalysts for activating carboxylic acids and generating new C–C, C–S, and C–Cl bonds. Carboxylic acids are ubiquitous in bioactive ...
