Synthesis of optically active-α-(imidazol-1-yl, purin-9-yl or uracil-1-yl) propanoic and succinic acid derivatives

Abstract An efficient route is reported to chiral propanoic and succinic acid derivatives 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.
