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).

Towards high-efficiency sorptive capture of radionuclides in solution and gas

As globalization and rapid population growth have raised global energy needs, the demand for nuclear energy has increased drastically. To make use of such energy more reliably, the efficient disposal of nuclear wastes has become a major challenge. With this in mind, numerous research efforts have been put to safely store, capture, and immobilize radioactive waste. As a result, a variety of sorbent materials with different physical, chemical, and structural properties have been invented or discovered. The maximum removal capacity of these sorbents were then assessed for a variety of radionuclides in soluble and/or gaseous forms. The pre-/post-synthetic modification of these sorbent materials has also been investigated intensively to help enhance their overall stability, tunability, and capacity without altering or damaging the main framework. In this review, we explored the performance of different materials for the sorption of most important radionuclide species including uranium, cobalt, europium, iodine, cesium, strontium, technetium, krypton, xenon, and argon. To begin with, we classified sorbent materials into three categories in light of their structural evolvement over time. We also described the critical factors to consider for the proper application of these categorized sorbents (e.g., sorption properties, structural characteristics, reversibility, and renewability). Finally, we discussed briefly the present limitations and future prospects of these technologies.

Discovery of a selective S1P1 receptor agonist efficacious at low oral dose and devoid of effects on heart rate

Gilenya (fingolimod, FTY720) was recently approved by the U.S. FDA for the treatment of patients with remitting relapsing multiple sclerosis (RRMS). It is a potent agonist of four of the five sphingosine 1-phosphate (S1P) G-protein-coupled receptors (S1P1 and S1P3-5). It has been postulated that fingolimod’s efficacy is due to S1P1 agonism, while its cardiovascular side effects (transient bradycardia and hypertension) are due to S1P3 agonism. We have discovered a series of selective S1P 1 agonists, which includes 3-[6-(5-{3-cyano-4-[(1-methylethyl)oxy] phenyl}-1,2,4-oxadiazol-3-yl)-5-methyl-3,4-dihydro-2(1H)-isoquinolinyl] propanoate, 20, a potent, S1P3-sparing, orally active S1P1 agonist. Compound 20 is as efficacious as fingolimod in a collagen-induced arthritis model and shows excellent pharmacokinetic properties preclinically. Importantly, the selectivity of 20 against S1P3 is responsible for an absence of cardiovascular signal in telemetered rats, even at high dose levels.

Discovery, synthesis, and structure-based optimization of a series of N -(tert -Butyl)-2-(N -arylamido)-2-(pyridin-3-yl) acetamides (ML188) as potent noncovalent small molecule inhibitors of the severe acute respiratory syndrome coronavirus (SARS-CoV) 3CL protease

A high-throughput screen of the NIH molecular libraries sample collection and subsequent optimization of a lead dipeptide-like series of severe acute respiratory syndrome (SARS) main protease (3CLpro) inhibitors led to the identification of probe compound ML188 (16-(R), (R)-N-(4-(tert-butyl)phenyl)-N- (2-(tert-butylamino)-2-oxo-1-(pyridin-3-yl)ethyl)furan-2-carboxamide, Pubchem CID: 46897844). Unlike the majority of reported coronavirus 3CLpro inhibitors that act via covalent modification of the enzyme, 16-(R) is a noncovalent SARS-CoV 3CLpro inhibitor with moderate MW and good enzyme and antiviral inhibitory activity. A multicomponent Ugi reaction was utilized to rapidly explore structure-activity relationships within S1?, S 1, and S2 enzyme binding pockets. The X-ray structure of SARS-CoV 3CLpro bound with 16-(R) was instrumental in guiding subsequent rounds of chemistry optimization. 16-(R) provides an excellent starting point for the further design and refinement of 3CLpro inhibitors that act by a noncovalent mechanism of action.

Structural Engineering of Two-Dimensional Covalent Organic Frameworks for Visible-Light-Driven Organic Transformations

Covalent organic frameworks (COFs) emerging as a novel kind of visible light-responsive organic semiconductor have attracted extensive research attention in the field of photocatalytic organic transformations. However, the key parameters affecting their photocatalytic properties are still not clear. In this work, a series of [3 + 3] COFs with similar two-dimensional hexagonal structure but different compositions are synthesized and employed as model materials for investigating the key factors affecting the photocatalytic properties in the visible-light-driven reductive dehalogenation reaction and the aerobic cross-dehydrogenative coupling reaction. In comparison with -H and -CF3, the -OH substituent in the aromatic ring could narrow the band gap of the COFs. The COFs with a triazine skeleton in the framework usually boost the photocatalytic activity, possibly because of the enhanced charge separation efficiency by the formation of a donor-acceptor domain. As a combined result of the narrow band gap, efficient charge separation, and high conductivity, the COF possessing both a -OH group and triazine skeleton shows the highest activity in the photocatalytic reductive dehalogenation reaction. Notably, COFs could be easily recovered and reused several times without the loss of crystallinity. Our primary results may shed light on the design of efficient COF-based semiconductors for photocatalytic organic transformations.

Asymmetric synthesis of 1-substituted 1,2,3,4-tetra-hydroisoquinolines by asymmetric electrophilic alpha-amidoalkylation reactions

An efficient method for the asymmetric synthesis of 1-substituted 1,2,3,4-tetrahydroisoquinolines via chiral N-acyliminium ions is presented. The N-acyl-1,2-dihydroisoquinolines (8) and (9) underwent smooth oxidation reactions with Ph3C+BF4- to give the chiral N-acylisoquinolinium ions (10) and (13), respectively. Stereoselective addition of organomagnesium and organozinc compounds to intermediates (10) and (13) provided the corresponding 1-substituted N-acyl-1,2-dihydroisoquinolines (11/12) and (14/15) in good yields. The diastereoselectivity of these reactions appeared to be dependent on the structure of the N-acyliminium ion intermediates (10) and (13) and on the nature of the trapping reagent with the zinc reagents in general leading to markedly improved stereoselectivities. Pure diastereomers were obtained by preparative HPLC and readily transformed into enantiopure 1-substituted 1,2,3,4-tetrahydroisoquinolines by catalytic hydrogenation and reductive removal of the chiral auxiliary.
