AbstractCoupling of protected-amino acid halides (chloride, fluoride) mediated by commercial anion exchange resin for the solution phase synthesis of peptides is described. The reaction was carried out in an organic medium, circumventing the use of an organic base or an inorganic base. The coupling is fast, clean and racemization free. The anion exchange resin functions as a solid-phase basic scavenger

A facile synthesis of acyl fluorides from carboxylic acids in a practical and byproduct-free manner was effected with commercially available KI/AgSCF3 reagents under conditions of high functional group tolerance, and the acyl fluoride intermediates were easily transformed to the corresponding esters, amides, and several carbon-carbon bond-forming products. This approach can be successfully applied
