The present invention relates to new compounds that show pharmacological dual activity towards the subunit α2δ of voltage-gated calcium channels (VGCC), especially the α2δ-1 subunit of voltage-gated calcium channels, and the µ-opiod receptor (MOR or mu-opioid). The invention is also related to the process for the preparation of said compounds as well as to compositions comprising them, and to their use as medicaments (formula (I)).

Herein, we report a one‐electron strategy for catalytic amide synthesis that enables the direct carbamoylation of (hetero)aryl bromides. This radical cross‐coupling approach, which is based on the combination of nickel and photoredox catalysis, proceeds at ambient temperature and uses readily available dihydropyridines as precursors of carbamoyl radicals. The method's mild reaction conditions make
The instant invention provides for substituted naphthyridine compounds that inhibit Akt activity. In particular, the compounds disclosed selectively inhibit one or two of the Akt isoforms, preferably Akt1. The invention also provides for compositions comprising such inhibitory compounds and methods of inhibiting Akt activity especially Akt1 by administering the compound to a patient in need of treatment of cancer.

The development of a convergent, chromatography-free synthesis of an allosteric Akt kinase inhibitor is described. The route comprised 17 total steps and was used to produce kilogram quantities of the target molecule. A key early transformation, for which both batch and flow protocols were developed, was formylation of a dianion derived by deprotonation and subsequent lithium-halogen exchange from a 2-bromo-3-aminopyridine precursor. Improved reaction yield and practicality were achieved in the continuous processing mode. Further significant process developments included the safe execution of a high temperature and pressure hydrazine displacement, separation of substituted cyclobutane diastereomers by means of chemoselective ester hydrolysis, and a late-stage Suzuki fragment coupling under mild conditions.
