Abstract
C-glycopyranosyl derivatives of six-membered heterocycles are scarcely represented in the chemical literature and the title 3-glycopyranosyl-1,2,4-triazines are completely unknown. In this paper, the first synthesis of this compound class is accomplished by the cyclocondensation of C-glycosyl formamidrazones and 1,2-dicarbonyl derivatives. In addition, the synthesis of C-glycopyranosyl 1,2,4-triazin-5(4H)-ones was also carried out by the transformation of the above formamidrazones with α-keto-carboxylic esters. Inverse electron demand Diels-Alder reactions of 3-glycopyranosyl-1,2,4-triazines with a bicyclononyne derivative yielded the corresponding annulated 2-glycopyranosyl pyridines.

Abstract
![]()
G-protein-coupled receptor 84 (GPR84) is a proinflammatory
orphan
G-protein-coupled receptor implicated in several inflammatory and
fibrotic diseases. Several agonist and antagonist ligands have been
developed that target GPR84; however, a noncompetitive receptor blocker
that was progressed to phase II clinical trials failed to demonstrate
efficacy. New high-quality antagonists are required to investigate
the pathophysiological role of GPR84 and to validate GPR84 as a therapeutic
target. We previously reported the discovery of a novel triazine GPR84
competitive antagonist 1. Here, we describe an extensive
structure–activity relationship (SAR) of antagonist 1 and also present in silico docking with supporting mutagenesis studies
that reveals a potential binding pose for this type of orthosteric
antagonist. Lead compound 42 is a potent GPR84 antagonist
with a favorable pharmacokinetic (PK) profile suitable for further
drug development.

Abstract
A synthetic strategy to pyrrolo[2,1-f][1,2,4]triazines is reported. We show that various synthetically easily accessible 1,2,4-triazines can be efficiently alkylated under mild conditions to provide the corresponding 1-alkyl-1,2,4-triazinium salts. These bench-stable salts serve as precursors to triazinium ylides, which react in 1,3-dipolar cycloadditions with electron-poor dipolarophiles to yield polysubstituted pyrrolotriazines in a single step.

Abstract
Triazines are an important class of six-membered aromatic heterocycles possessing three nitrogen atoms, resulting in three types of regio-isomers: 1,2,4-triazines (a-triazines), 1,2,3-triazines (v-triazines), and 1,3,5-triazines (s-triazines). Notably, the application of triazines as cyclic aza-dienes in inverse electron-demand Diels-Alder (IEDDA) cycloaddition reactions has been established as a unique and powerful method in N-heterocycle synthesis, natural product preparation, and bioorthogonal chemistry. In this review, we comprehensively summarize the advances in the construction of these triazines via annulation and ring-expansion reactions, especially emphasizing recent developments and challenges. The synthetic transformations of triazines are focused on IEDDA cycloaddition reactions, which have allowed access to a wide scope of heterocycles, including pyridines, carbolines, azepines, pyridazines, pyrazines, and pyrimidines. The utilization of triazine IEDDA reactions as key steps in natural product synthesis is also discussed. More importantly, a particular attention is paid on the bioorthogonal application of triazines in fast click ligation with various strained alkenes and alkynes, which opens a new opportunity for studying biomolecules in chemical biology.

Abstract
A controllable Rh(III)-catalyzed C-H arylation and dealcoholization of benzimidates with arylboronic esters was developed, delivering various biphenyl-2-carbonitriles and biphenyl-2-carbimidates by simply tuning the reaction conditions. This approach features high efficiency, good functional group tolerance, and easy operation. It also provides an alternative pathway to thoroughly exploit the directing group in transition-metal-catalyzed C-H activations.
