Abstract:
PROBLEM TO BE SOLVED: To readily obtain the subject compound useful as a ligand for a metabotropic glutamate receptor of group II in high yield in a diastereomeric and enantiomeric purity by using a specific intermediate. SOLUTION: The carbonyl group of a compound of formula I (R" and R"' are each benzyl or a lower alkyl) is reduced to a hydroxyl group to give a compound or formula II or III. If desired, the compound of formula II is alkylated, alkenylated or benzylated, the azido group is reduced to an amino group and the ester group is hydrolysed.
