The invention relates to a compound of formula (I) wherein R1 to R4 are defined as in the description and in the claims. The compound of formula (I) is a CB2 agonist and can be used as an active ingredient in a medicament.
practical synthesis of 1 involving a catalytic enantioselective construction of the quaternary carbon from imine 10 (derived from 13 and 14) and alkyl iodide 5 using Maruoka’s chiral catalyst 11 is described. This asymmetric alkylation followed by hydrolysis to amino acid 9 was accomplished in good yield with high chemical purity (>98%) and chiral purity (>96% ee). The improved synthesis enabled production
