Visible Light-Mediated Direct Decarboxylative C-H Functionalization of Heteroarenes

The direct visible light-mediated C-H alkylation of heteroarenes using aliphatic carboxylic acids is reported. This mild method proceeds at low catalyst loadings (0.5 mol %) and has a high functional group tolerance and a broad substrate scope. Notably, functionalization of (iso)quinoline, pyridine, phthalazine, benzothiazole, and other heterocyclic derivatives with both cyclic and acyclic primary, secondary, and tertiary carboxylic acids as well as amino and fatty acids proceeded under the standard conditions at room temperature. This protocol enables the rapid conversion of abundant feedstock materials into medically relevant “drug-like” moieties.

Fast, solvent-free asymmetric alkynylation of prochiral sp3 C-H bonds in a ball mill for the preparation of optically active tetrahydroisoquinoline derivatives

Solvent-free asymmetric cross-dehydrogenative-coupling (CDC) reaction between the sp3 C-H bond of prochiral CH2 and terminal alkynes was first studied under High-Speed Ball-Milling conditions. A series of optical active 1-alkynyl tetrahydroisoquinoline derivatives were achieved by using recoverable copper balls together with PyBox chiral ligand in the presence of 2,3-dichloro-5,6- dicyano-1,4-benzoquinone (DDQ). All coupling products were obtained in good yields at short reaction time with enantiomeric excesses up to 79%.

CeO2-Catalyzed C-H Functionalization of N-Aryltetrahydroisoquinolines: An Aerobic Cross-Dehydrogenative Coupling Reaction between Two sp3 C-H Bonds

CeO2 has been used as heterogeneous catalyst for carbon-carbon bond formation via cross-dehydrogenative coupling (CDC). It works efficiently for oxidative C?C bond formation between N-aryltetrahydroisoquinoline derivatives and a carbon nucleophile nitroalkane and acetone under aerobic conditions. This is the first report of CeO2 as a low temperature catalyst for the carbon-carbon bond formation reaction between two sp3 C?H bonds.

Enantioselective synthesis of 1-Aryl-substituted tetrahydroisoquinolines employing imine reductase

Tetrahydroisoquinolines (THIQs) with a C1-aryl-substituted groups are common in many natural and synthetic compounds of biological importance. Currently, their enantioselective synthesis are primarily reliant on chemical catalysis. Enzymatic synthesis using imine reductase is very attractive, because of the cost-effectiveness, high catalytic efficiency, and enantioselectivity. However, the steric hindrance of the 1-aryl substituents make this conversion very challenging, and current successful examples are mostly restricted to the simple alkyl-THIQs. In this report, through extensive evaluation of a large collection of IREDs (including 88 enzymes), we successfully identified a panel of steric-hindrance tolerated IREDs. These enzymes are able to convert meta- and para-substituted chloro-, methyl-, and methoxyl-benzyl dihydroisoquinolines (DHIQs) into corresponding R- or S- THIQs with very high enantioselectivity and conversion. Among them, the two most hindrance-tolerated enzymes (with different stereospecificity) are also able to convert ortho-substituted chloro-, methyl-, and methoxyl-benzyl DHIQs and dimethoxyl 1-chlorobenzyl-DHIQs with good enantiometric excess. Furthermore, using in silico modeling, a highly conserved tryptophan residue (W191) was identified to be critical for substrate accommodation in the binding cavity of the S-selective IRED (IR45). Replacing W191 with alanine can dramatically increase the catalytic performance by decreasing the Km value by 2 orders of magnitude. Our results provide an effective route to synthesize these important classes of THIQs. Moreover, the disclosed sequences and substrate binding model set a solid basis to generate more-efficient and broad-selective enzymes via protein engineering.

Development of Gleevec Analogues for Reducing Production of beta-Amyloid Peptides through Shifting beta-Cleavage of Amyloid Precursor Proteins

Imatinib mesylate, 1a, inhibits production of beta-amyloid (Abeta) peptides both in cells and in animal models. It reduces both the beta-secretase and gamma-secretase cleavages of the amyloid precursor protein (APP) and mediates a synergistic effect, when combined with a beta-secretase inhibitor, BACE IV. Toward developing more potent brain-permeable leads, we have synthesized and evaluated over 75 1a-analogues. Several compounds, including 2a-b and 3a-c, inhibited production of Abeta peptides with improved activity in cells. These compounds affected beta-secretase cleavage of APP similarly to 1a. Compound 2a significantly reduced production of the Abeta42 peptide, when administered (100 mg/kg, twice daily by oral gavage) to 5 months old female mice for 5 days. A combination of compound 2a with BACE IV also reduced Abeta levels in cells, more than the additive effect of the two compounds. These results open a new avenue for developing treatments for Alzheimer’s disease using 1a-analogues.
