Pr. Birkett et al., SYNTHESIS OF OPTICALLY-ACTIVE ALPHA-(IMIDAZOL-1-YL, PURIN-9-YL OR URACIL-1-YL) PROPANOIC AND SUCCINIC ACID-DERIVATIVES, Tetrahedron, 49(47), 1993, pp. 11029-11036
An efficient route is reported to chiral propanoic and succinic acid d
erivatives substituted in the alpha-position with adenine, hypoxanthin
e 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.
