Four isomers of the L-aspartyl-D-alanine fenchyl esters were prepared as potential peptide sweeteners. L-Aspartyl-D-alanine (+)-α-fenchyl ester and L-aspartyl-D-alanine (-)-β-fenchyl ester showed sweetness with potencies 250 and 160 times higher than that of sucrose, respectively. In contrast, L-aspartyl-D-alanine (+)-β-fenchyl ester and L-aspartyl-D-alanine (-)-α-fenchyl ester had the highest sweetness potencies at 5700 and 1100 times that of sucrose, respectively. In particular, L-aspartyl-D-alanine (-)-α-fenchyl ester had an excellent sweetness quality, but L-aspartyl-D-alanine (+)-β-fenchyl ester did not have an excellent quality of sweetness because it displayed an aftertaste caused by the strong sweetness.
