Intermolecular Nucleophilic Addition of N-Diaminophosphinoyl-Protected alpha-Carbanions Derived from Secondary Amines to Arynes: Synthesis of 1-Aryl-1,2,3,4-tetrahydroisoquinolines

Various 1-aryl-1,2,3,4-tetrahydroisoquinolineswere synthesized by coupling alpha-amino carbanions, derived from N-protected secondary amines, with in situ generated arynes. Different N-protecting/activating groups were investigated and it was found that only the N-bis(dimethylamino)phosphinoyl group is suitable to obtain the title compounds.This procedure has also been used for an efficient one-pot synthesis of the drug (±)-FR115427.

NHC-catalyzed Redox-Neutral Aza-Benzoin Reaction of Aldehydes with Tetrahydroisoquinolines

Tetrahydroisoquinoline derivatives are useful synthetic intermediates, which play an important role in the preparation of natural products, pharmaceuticals and other materials. Herein, we report an unprecedented redox-neutral aza-benzoin protocol to construct such scaffold. Upon exposure of tetrahydroisoquinolines to aromatic aldehydes in the presence of an NHC catalyst, the C-1 acylated tetrahydroisoquinolines were obtained in moderate to good yields.

Doping metal-organic frameworks for water oxidation, carbon dioxide reduction, and organic photocatalysis

Catalytically competent Ir, Re, and Ru complexes H2L 1-H2L6 with dicarboxylic acid functionalities were incorporated into a highly stable and porous Zr6O 4(OH)4(bpdc)6 (UiO-67, bpdc = para-biphenyldicarboxylic acid) framework using a mix-and-match synthetic strategy. The matching ligand lengths between bpdc and L1-L 6 ligands allowed the construction of highly crystalline UiO-67 frameworks (metal-organic frameworks (MOFs) 1-6) that were doped with L 1-L6 ligands. MOFs 1-6 were isostructural to the parent UiO-67 framework as shown by powder X-ray diffraction (PXRD) and exhibited high surface areas ranging from 1092 to 1497 m2/g. MOFs 1-6 were stable in air up to 400 C and active catalysts in a range of reactions that are relevant to solar energy utilization. MOFs 1-3 containing [Cp*Ir III(dcppy)Cl] (H2L1), [Cp*Ir III(dcbpy)Cl]Cl (H2L2), and [Ir III(dcppy)2(H2O)2]OTf (H 2L3) (where Cp* is pentamethylcyclopentadienyl, dcppy is 2-phenylpyridine-5,4?-dicarboxylic acid, and dcbpy is 2,2?-bipyridine-5,5?-dicarboxylic acid) were effective water oxidation catalysts (WOCs), with turnover frequencies (TOFs) of up to 4.8 h -1. The [ReI(CO)3(dcbpy)Cl] (H 2L4) derivatized MOF 4 served as an active catalyst for photocatalytic CO2 reduction with a total turnover number (TON) of 10.9, three times higher than that of the homogeneous complex H 2L4. MOFs 5 and 6 contained phosphorescent [Ir III(ppy)2(dcbpy)]Cl (H2L5) and [RuII(bpy)2(dcbpy)]Cl2 (H2L 6) (where ppy is 2-phenylpyridine and bpy is 2,2?-bipyridine) and were used in three photocatalytic organic transformations (aza-Henry reaction, aerobic amine coupling, and aerobic oxidation of thioanisole) with very high activities. The inactivity of the parent UiO-67 framework and the reaction supernatants in catalytic water oxidation, CO2 reduction, and organic transformations indicate both the molecular origin and heterogeneous nature of these catalytic processes. The stability of the doped UiO-67 catalysts under catalytic conditions was also demonstrated by comparing PXRD patterns before and after catalysis. This work illustrates the potential of combining molecular catalysts and MOF structures in developing highly active heterogeneous catalysts for solar energy utilization.

Potassium Alkylpentafluorosilicates, Primary Alkyl Radical Precursors in the C-1 Alkylation of Tetrahydroisoquinolines

In this study, we demonstrate that potassium alkylpentafluorosilicates (RSiF5K2) are efficient primary alkyl radical precursors for selective C(sp3)-C(sp3) bond-forming reactions. RSiF5K2 reagents are white, free-flowing solids and are moisture and air stable. This class of reagents enables the direct C-1 alkylation of tetrahydroisoquinolines under mild conditions via single-electron transfer. The broad substrate scope of both alkylpentafluorosilicates and tetrahydroisoquinolines is tolerated in this transformation. Both radical scavenger and EPR capture experiments show that the primary radical is generated by the oxidation of RSiF5K2. A mechanism involving alkyl radical addition to an iminium salt followed by reduction by an amine is proposed.
