An efficient route is reported to chiral propanoic and succinicacidderivatives substituted in the α-position with adenine, hypoxanthine and uracil groups. These nucleic acid base derivatives are obtained in optically pure form by a procedure which starts from an amino acid as a convenient chiral synthon.

The (R)-2-(adenin-9-yl)propanoic acid was prepared from adenine and (S)-ethyl lactate by using the triphenyl phosphine-diethyl azodicarboxylate system. The (R)-2-(thymin-1-yl)-propanoic acid, (R)-2-(cytosin-1-yl)propanoic acid, and (R)-2-(hypoxanthin-9-yl)propanoic acid were also prepared.
