Abstract

Dipeptide esters (I; X = Ph or PhOH. R = C1-7 alkyl conformation of which is L-L) were isolated from the impurities-contained dipeptide esters(II). To isolate the I,II was distributed in water and alkanol soln., and I was isolated from the alkanol layer. Thus, 3.8g PBr3 an 5g(CH3CO)2O were added in the suspension consisting of 10g L-aspartic acid and 40ml. propionic acid, and stirred for 8hr at room temp. to give ppt. The ppt was washed with ether followed by filtration, and dried.
