Abstract

L-Amino acids were converted into sulfonamides by reaction with phenylsulfonyl chloride in a basic medium. Subsequent treatment of these sulfonamides with 1H-benzotriazole (BtH) and thionyl chloride at room temperature yielded benzotriazole–amino acid–benzenesulfonamide conjugates with yields ranging from 42% to 68%. Furthermore, the reaction of the benzotriazole derivatives with free glycine and free phenylalanine resulted in the formation of (phenylsulfonyl)dipeptides.
