Abstract

It is seen from Table 1 that the stereoisomers of the intermediate and final compounds are close in absolute size and opposite in sign for the value of the specific rotation. Furthermore, the constants of diketopiperazine L-(V) synthesized by the proposed scheme agree well with the constants of this substance given in the literature and obtained in [i, 8] by other means. It is necessary to consider the possibility of racemization at the stage of reducing ...
