An efficient method for the synthesis of phenacyl ester-protected dipeptides using neutral alumina-supported sodium carbonate 'Na2CO3/n-Al2O3'
In the synthesis of dipeptides (Boc-AA1-AA2-OPac: AA1 and AA2 represent amino acids) protected by phenacyl (Pac) ester, amines and solid bases as the base for the conversion of the trifluoroacetic acid (TFA) sal
