N-Alkyl and N-aryl-isoindolinones were prepared by a dioxane-mediated oxidation of isoindoline precursors. The transformation exhibits unique chemoselectivity for isoindonlines. A chiral tertiary (3)-benzylic position was not racemized during oxidation, and methyl indoprofen was prepared by late stage oxidation. Mechanistic studies suggest a selective H atom transfer, which avoids many known oxidation (by-)products of isoindolinones.

An efficient C1-difluoromethylation of tetrahydroisoquinolenes was achieved using TMSCF2SPh as a difluoromethylating agent and 2,2,6,6-tetramethylpiperidine-1-oxoammonium tetrafluoroborate (TEMPO+BF4-) as an oxidant. The process provides an access to a variety of C1-difluoro(phenylsulfanyl)methylated tetrahydroisoquinoline adducts in good yields. These adducts were employed as key precursors for preparing fluorinated pyrrolo[2,1-a]isoquinoline and benzo[a]quinolizidines.

A practical metal-free oxidative Ugi-type three-component assembly has been achieved efficiently, employing a tertiary-amine-derived iminium ion as an imine surrogate, N-hydroxyimide as an acid surrogate, and DEAD as an oxidant. This dual-surrogate Ugi variant proceeded with a broad substrate scope and desired functional group tolerance, leading to a wide range of N-alkyl-N-acyl aminophthalimide and N-alkyl-N-acylaminosuccinimide derivatives in good isolated yields.

We have exploited a bis(1,10-phenanthroline)copper(I) visible light photocatalyst (VLP), [Cu(dap)2]+, to effect the direct alpha-C-H functionalization of amines. To our knowledge, this represents the first example of the oxidation of amines that are ultimately incorporated into synthetic targets by a copper(I) VLP. We have utilized this approach to rapidly prepare unprecedented octahydroisoquinolino[2,1-a]pyrrolo[3,4-c]quinoline frameworks and exploited this process to synthesize a novel aglycone analogue of the natural product incargranine B. Most significantly, our studies suggest that the presence of trifluoroacetic acid (TFA) is crucial in mediating the aerobic oxidative quenching of a putative photoexcited copper(I) species involved in the catalytic cycle.

Abstract: Alkynylation reactions of N-protected tetrahydroisoquinolines have been performed using several different protocols of cross dehydrogenative coupling. Initially, a CuCl-catalyzed method was investigated, which worked well with three different N-protecting groups, namely phenyl, PMP, and benzyl and t-BuOOH as oxidant in acetonitrile as solvent. The peroxide could then be replaced by simple air and acetonitrile for water, leading to an overall very environmentally friendly protocol. Finally, a decarboxylative alkynylation protocol starting from alkynoic acids was also developed using again air as oxidant. This avoids the use of gaseous alkynes in the introduction of short-chained alkyne substituents. Graphical abstract: [Figure not available: see fulltext.]

A novel tetrazole-containing triphenylamine-based MOF {TBA[Cu2(TPA)]}·CH3CN (Cu?TPA; TBA = tetrabutylammonium cation) has been solvothermally synthesized by the reaction of CuCl2·2H2O, tris(4-(2H-tetrazol-5-yl)phenyl)amine (H3TPA) and (TBA)4[W10O32] and structurally characterized by IR spectrum, UV?Vis spectrum, fluorescence analysis, powder X-ray diffraction (PXRD) and single-crystal X-ray diffraction. More interestingly, Cu?TPA exhibits remarkable heterogeneous photocatalytic property and promotes the oxidative C[sbnd]C coupling reaction under mild conditions. The high catalytic efficiency, high stability and good recyclability of the photocatalyst Cu?TPA demonstrate the superiority of the tetrazole-containing triphenylamine-based MOF over homogeneous systems and other noble-metal-catalyzed methods.
