be constructed in only two steps. It complexes Pd(OAc)2 forming a precursor of a very active catalyst useful for Suzuki–Miyaura cross-couplings of functionalized substrates. By a combination of pre-activation, used together with the uncommon solvent EtOAc, the resulting catalyst system is effective at loadings in the ppm (0.1–0.5 mol%) range with highly functionalized reaction partners.

Pd(II)-catalyzed α-C(sp(3))-Harylation of pyrrolidines, piperidines, azepanes, and N-methylamines with arylboronic acids has been developed for the first time. This transformation is applicable to wide arrays of pyrrolidines and boronic acids, including heteroaromatic boronic acids. A diastereoselective one-pot heterodiarylation of pyrrolidines has also been achieved.

The present disclosure relates to certain amine derivatives of fused bicyclic heterocycles that inhibit the amine reuptake function of the biogenic amine transporters, dopamine transporter (DAT), serotonin transporter (SERT) and norepinephrine transporter (NET). Compounds of the present disclosure are potent inhibitors of the reuptake of dopamine (DA), serotonin (5-hydroxytryptamine, 5-HT) and norepinephrine (NE) with full or partial maximal efficacy. The compounds with partial maximal efficacy in inhibiting reuptake of all three biogenic amines are herein referred to as partial triple uptake inhibitors (PTRIs). Compounds of the present disclosure are useful for treating depression, pain and substance abuse and relapse to substance abuse and addiction to substances such as cocaine, methamphetamine, nicotine and alcohol. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

the C(sp2)–C(sp3) Suzuki–Miyaura cross coupling of (hetero)arylboronic acids with alkyl bromides. With 5 mol % of the optimal (MeOMeFI)Ni(Aryl)(DMAP) precatalyst, the scope of the cross-coupling reaction was established and included a variety of (hetero)arylboronic acids and alkyl bromides (>50 examples, 33–97% yield).
