We have recently developed palladium-catalyzed methods for direct arylation of indoles (and other azoles) wherein high C-2 selectivity was observed for both free (NH)-indole and (NR)-indole. To provide a rationale for the observed selectivity (“nonelectrophilic” regioselectivity), mechanistic studies were conducted, using the phenylation of 1-methylindole as a model system. The reaction order was determined for iodobenzene (zero order), indole (first order), and the catalyst (first order). These kinetic studies, together with the Hammett plot, provided a strong support for the electrophilic palladation pathway. In addition, the kinetic isotope effect (KIEH/D) was determined for both C-2 and C-3 positions. A surprisingly large value of 1.6 was found for the C-3 position where the substitution does not occur (secondary KIE), while a smaller value of 1.2 was found at C-2 (apparent primary KIE). On the basis of these findings, a mechanistic interpretation is presented that features an electrophilic palladation of indole, accompanied by a 1,2-migration of an intermediate palladium species. This paradigm was used to design new catalytic conditions for the C-3 arylation of indole. In case of free (NH)-indole, regioselectivity of the arylation reaction (C-2 versus C-3) was achieved by the choice of magnesium base.

Mutations in leucine-rich repeat kinase-2 (LRRK2) are the most common genetic cause of Parkinson’s disease (PD). The most frequent kinase-enhancing mutation is the G2019S residing in the kinase activation domain. This opens up a promising therapeutic avenue for drug discovery targeting the kinase activity of LRRK2 in PD. Several LRRK2 inhibitors have been reported to date. Here, we report a selective, brain penetrant LRRK2 inhibitor and demonstrate by a competition pulldown assay in vivo target engagement in mice.

A metal-free C-C bond formation method via the oxidative cross-coupling reaction of isochroman and indole derivatives was established. Various alpha-fuctionalized cyclic ethers were achieved in satisfactory yields using di-tert-butyl peroxide (DTBP) as the oxidant. This method is also a potentially efficient strategy for the construction of cyclic ether-containing targets.

2-Bromoindoles were readily prepared through a facile Cs2CO 3-promoted intramolecular cyclization of 2-(gem-bromovinyl)-N- methylsulfonylanilines in excellent yields under transition-metal-free conditions. This methodology could be extended to the synthesis of corresponding 2-chloroindoles. The reaction mechanism suggested that cyclization occurs through a key intermediate, phenylethynyl bromide, followed by cyclization in one-pot. The Royal Society of Chemistry.

A new simple catalytic system consisting of copper-aluminium and hydrotalcite (CuAl-HT) has been developed using a facile one-pot method without harm to the environment. The catalyst was characterized using TEM, XRD and XPS. It could be used as an efficient catalyst for the synthesis of both indole and phenyl ether. As expected, the catalyst afforded high catalytic activity for the selective synthesis of indole via intramolecular dehydrogenative N-heterocyclization of 2-(2-aminophenyl)ethanol. Meanwhile, it also exhibited superior catalytic properties for an Ullmann-type coupling reaction to synthesise phenyl ether from iodobenzene and phenol. The CuAl-HT catalyst showed higher activity than conventional catalysts based on copper and could be recycled several times with stable catalytic activity. This procedure has real economic advantages since no expensive materials were used.

5-HT4 receptor agonists such as tegaserod have demonstrated efficacy in the treatment of constipation predominant irritable bowel syndrome (IBS-C), a highly prevalent disorder characterized by chronic constipation and impairment of intestinal propulsion, abdominal bloating, and pain. The 5-HT 4 receptor binding site can accommodate functionally and sterically diverse groups attached to the amine nitrogen atom of common ligands, occupying what may be termed a “secondary” binding site. Using a multivalent approach to lead discovery, we have investigated how varying the position and nature of the secondary binding group can be used as a strategy to achieve the desired 5-HT4 agonist pharmacological profile. During this study, we discovered the ability of amine-based secondary binding groups to impart exceptional gains in the binding affinity, selectivity, and functional potency of 5-HT4 agonists. Optimization of the leads generated by this approach afforded compound 26, a selective, orally efficacious 5-HT4 agonist for the potential treatment of gastrointestinal motility-related disorders.
