The present invention provides compounds of formula (I) and pharmaceutically acceptable salts thereof, wherein R1, R2, R3, R4a and R4b are as defined in the specification, processes for their preparation, pharmaceutical compositions containing them and their use in therapy. The compounds of formula (I) are mGluR7 modulators.
The Rh(III)-catalyzed amidation of C(sp2)-H bonds has been reported by employing the N-methoxyamide as a novel amino source. An excellent level of functional group tolerance can be achieved when N-methoxyamide derivatives are used as the amidating reagents. Importantly, several known bioactive compounds such as Aminalon, Pregabalin, Gabapentin, and Probenecid can be transformed to effective amidating

the DGCN α-center permitting the utilization of a readily available l-amino acid precursor to the d α-hydroxy carboxylicacid residue. An alternative and similarly attractive approach of direct macrolactonization of a substrate necessarily incorporating a d-DGCN subunit proved viable albeit less effective. Biological evaluation in cellular assays for vascular adhesion molecule expression confirmed that

Herein, we report a urea derived directing group for mild and highly selective oxidative CâH bond olefination. Subsequent intramolecular Michael addition affords dihydroquinazolinones in good yields. The NâO bond of the urea substrate exhibits superior oxidative behaviour compared to a variety of other external oxidants.
