Abstract
The present invention relates to novel compounds of Formula I and their use in therapeutic treatments. The invention further relates to a novel chiral synthesis of 5,6,7,(8-substituted)-tetrahydro-[1,2,4]triazolo[4,3-a]pyrazines using N-sp3 protective groups. The invention also provides intermediates for use in the synthesis of compounds of Formula I.
