International audience; An efficient access to 4-aryl imidazole scaffolds is described in two steps and one operation. Cyanoaryl-imidazolines are easily obtained by a (3 + 2) heterocyloaddition involving cyanobenzenes as dipolarophiles and a non-stab

International audience; A simple, two-step procedure to convert α,α-difluorinated H-phosphinic acids into the corresponding H-phosphinothioates is described. The usefulness of these species is demonstrated by their transformation into difluorinated

International audience; Nucleophilic enamines add spontaneously on heteroarenes 3-nitroindole and benzofuran to form a new C–C bond. With nitroindole (1) and enamine (2a), an unprecedented dearomatizing formal ene reaction occurs in a totally regio

Dearomatization of electron-poor benzofurans is possible through involvement of the aromatic 2,3-carbon-carbon double bond as dienophile in normal electron demand [4 + 2] cycloadditions. The tricyclic heterocycles thereby produced bear a quaternary c

Activation by high pressure allows 3-nitroindole and 3-nitropyrrole derivatives to behave as electron-poor heterodienes in multicomponent domino [4+2]/[3+2] cycloaddition processes. The primary [4+2] inverse demand cycloaddition appears to be complet

[reaction: see text] Selanylated difluoromethylphosphonates and difluoromethylphosphonothioates are good precursors to phosphonodifluoromethyl and phosphonothiodifluoromethyl radicals, respectively. When generated in the presence of alkenes and a hyd

Alcohols are solvents of choice to react boronates, aldehydes and either primary or secondary amines. Thus, while the reaction proceeds sluggishly, or not at all, in aprotic solvents, the desired aminoacids are in most cases obtained in high yields w

An improved, convergent synthesis of CB92834 is relying on a Suzuki cross-coupling reaction and easily allows multigram-scale preparation of the compound. The approach features three highly stereoselective steps.
