Enantioselective Aerobic Oxidative C(sp3)-H Olefination of Amines via Cooperative Photoredox and Asymmetric Catalysis

A cooperative photoredox and asymmetric catalysis for the enantioselective aerobic oxidative C(sp3)-H olefination of tetrahydro-beta-carbolines (THCs) is reported. This method, which is also effective for tetrahydroisoquinolines (THIQs), features a triple-catalyst strategy, involving a dicyanopyrazine-derived chromophore (DPZ) as the metal-free photoredox catalyst, a chiral Lewis base catalyst, and an inorganic salt cocatalyst. The current protocol provides straightforward access to a series of valuable alpha-substituted THCs and THIQs in high yields with excellent regio- and enantioselectivities (up to 95% ee).

Hypoxia-selective antitumor agents. 12. Nitrobenzyl quaternary salts as bioreductive prodrugs of the alkylating agent mechlorethamine

A series of benzene-substituted analogues of the novel hypoxia-selective cytotoxin N,N-bis(2-chloroethyl)-N-methyl-N-(2-nitrobenzyl)ammonium chloride (3a), together with three corresponding tetrahydroisoquinolinium ‘cyclic’ analogues 21a-23a and two naphthalene derivatives (19a and 20a), have been prepared and evaluated for cytotoxicity in cultured mammalian tumor cells under aerobic and hypoxic conditions. The parent compound 3a has a one- electron reduction potential of -358 mV and undergoes reductively-induced fragmentation to release the nitrogen mustard mechlorethamine. The compounds were prepared by halogenation (SOCl2) of the corresponding quaternary diols, which in turn were synthesized from N-methyldiethanolamine and substituted nitrobenzyl chlorides. The reduction potentials of the benzene-substituted compounds were generally well-predicted by Hammett substituent relationships. All of the compounds were much more toxic toward repair-deficient UV4 cells than the corresponding wild-type AA8 cells, as expected if the active cytotoxic species is a DNA alkylating agent. They were also more toxic toward the human cell lines EMT6 and FME compared to AA8, but the reasons for this are not known. Analogues of 3a substituted in the phenyl ring with electron- donating substituents provided compounds with widely differing selectivities for hypoxic AA8 cells, ranging from no selectivity for the 3-Me compound 9a to 3000-fold (at least as great as that of the parent 3a) for the 4-OMe compound 14a. The naphthalene derivatives 19a and 20a and the tetrahydroisoquinolinium compounds 21a-23a showed no hypoxic selectivity. Selective chemical reduction of 22a and 23a with nickel boride resulted in isolation of the corresponding stable amine derivatives, indicating that reduction of these compounds does not result in fragmentation. The reason(s) for the marked differences in hypoxic selectivity of the nitrobenzyl quaternary mustards is unknown, but may reflect differences in radical chemistry, cell uptake, or sensitivity to enzymatic reduction.

Discovery of Tetrahydroisoquinoline-Containing CXCR4 Antagonists with Improved in Vitro ADMET Properties

CXCR4 is a seven-transmembrane receptor expressed by hematopoietic stem cells and progeny, as well as by ?48 different cancers types. CXCL12, the only chemokine ligand of CXCR4, is secreted within the tumor microenvironment, providing sanctuary for CXCR4+ tumor cells from immune surveillance and chemotherapeutic elimination by (1) stimulating prosurvival signaling and (2) recruiting CXCR4+ immunosuppressive leukocytes. Additionally, distant CXCL12-rich niches attract and support CXCR4+ metastatic growths. Accordingly, CXCR4 antagonists can potentially obstruct CXCR4-mediated prosurvival signaling, recondition the CXCR4+ leukocyte infiltrate from immunosuppressive to immunoreactive, and inhibit CXCR4+ cancer cell metastasis. Current small molecule CXCR4 antagonists suffer from poor oral bioavailability and off-target liabilities. Herein, we report a series of novel tetrahydroisoquinoline-containing CXCR4 antagonists designed to improve intestinal absorption and off-target profiles. Structure-activity relationships regarding CXCR4 potency, intestinal permeability, metabolic stability, and cytochrome P450 inhibition are presented.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Enantioselective cross dehydrogenative coupling reaction catalyzed by Rose Bengal incorporated-Cu(I)-dimeric chiral complexes

A novel dimeric chiral Cu(I) amino alcohol based in-situ generated catalyst in combination with Rose Bengal as a photo-redox catalyst were used for the first time for asymmetric cross dehydrogenative coupling of N-aryl tetrahydroisoquinoline with terminal alkynes enroute for propargylic amines synthesis using molecular oxygen as a terminal oxidant. This methodology provides an atom economical and green way to access diversified optically active alkynylation product selectively at C1-position of N-aryl tetrahydroisoquinoline under moderate conditions with high enantioselectivity (up to 99%) and excellent yield (up to 90%).

Gold Particles Supported on Amino-Functionalized Silica Catalyze Transfer Hydrogenation of N-Heterocyclic Compounds

In this work we demonstrate that exceptionally small gold particles (d=0.6¡À0.2 nm) supported on amino-functionalized mesoporous silicate SBA-15 are highly active in transfer hydrogenation of structurally diverse unsaturated N-heterocyclic compounds. The heterocyclic ring is reduced selectively. The gold particles aggregate to a diameter of 4?5 nm in the presence of formic acid/triethylamine (hydrogen donor) during the first catalytic run. In subsequent cycles the nanoparticles maintain their size, yielding a very stable catalytic system that was recycled more than five times. In contrast, analogous SBA catalysts featuring larger (?5?35 nm) gold particles are not active. Excess formic acid also leads to the formation of formamide derivatives of the products of hydrogenation, which can be deformylated quantitatively. Fifteen structurally different substrates, including the scaffolds of quinoline, isoquinoline, quinoxaline, acridine, phenanthroline, quinazoline, and phenanthridine are hydrogenated and deformylated to give the amine products in >90% overall yield. Deuterium labeling experiments indicate that 1,2-addition with subsequent disproportionation of the formed intermediate is the preferred reaction path over the 1,4-addition one, suggesting the participation of a gold hydride species. (Figure presented.).
