Synthesis of 3-hetarylpyrroles by Suzuki–Miyaura cross-coupling
1-[tert-Butyl(diphenyl)silyl]pyrrol-3-ylboronic acid was obtained from pyrrole in three steps. Its Suzuki–Miyaura cross-coupling with functionalized pyridinyl and pyrimidinyl bromides afforded new promising 3-hetaryl-1H-pyrroles.

A Visible Light-Mediated Regioselective Halogenation of Anilides and Quinolines by Using a Heterogeneous Cu-MnO Catalyst
A simple and practical heterogeneous Cu-MnO catalyzed regioselective halogenation of anilides and quinolines under irradiation with household 40 W incandescent lamp was developed. This method uses a recyclable Cu-MnO catalyst, acetonitrile as an industrially friendly solvent, and economic N-halo succinimides as a halogenating source. The reaction is scalable and well tolerated with a broad range of functional groups.
The present invention relates to compounds of Formula (I), which are DYRK1A and/or DYRK1B inhibitors,and their use in the treatment of neurodegenerative disorders such as Alzheimer's disease (AD) and Parkinson's disease (PD), metabolic disorders such as M

Novel indole and azaindole (pyrrolopyridine) cannabinoid (CB) receptor agonists: Design, synthesis, structure-activity relationships, physicochemical properties and biological activity
The discovery, synthesis and structure-activity relationship (SAR) of a novel series of cannabinoid 1 (CB1) and cannabinoid 2 (CB 2) receptor ligands are reported. Based on the aminoalkylindole class of cannabinoid receptor agonists, a biphenyl moiety was introduced as novel lipophilic indole 3-acyl substituent in 11-16. Furthermore, the 3-carbonyl tether was replaced with a carboxamide linker in 17-20 and the azaindole (pyrrolopyridine) nucleus was designed as indole bioisostere with improved physicochemical properties in 21-25. Through these SAR efforts, several high affinity CB1/CB2 dual cannabinoid receptor ligands were identified. Indole-3-carboxamide 17 displayed single-digit nanomolar affinity and ~80 fold selectivity for CB1 over the CB2 receptor. The azaindoles displayed substantially improved physicochemical properties (lipophilicity; aqueous solubility). Azaindole 21 elicited potent cannabinoid activity. Cannabinoid receptor agonists 17 and 21 potently modulated excitatory synaptic transmission in an acute rat brain slice model of cannabinoid receptor-modulated neurotransmission.

CONDENSED HETEROAROMATIC RING SYSTEMS. XXII. SIMPLE AND GENERAL SYNTHESIS OF 1H-PYRROLOPYRIDINES
Four kinds of 1H-pyrrolopyridines having no substituent were simply and easily synthesized by the palladium-catalyzed reaction of easily available nitropyridine derivatives with (Z)-1-ethoxy-2-tributylstannylethene as a key reaction.
