Enantioselective reductive coupling of 1,3-enynes to heterocyclic aromatic aldehydes and ketones via rhodium-catalyzed asymmetric hydrogenation: Mechanistic insight into the role of Bronsted acid additives

Hydrogenation of 1,3-enynes 1a-e in the presence of heterocyclic aromatic aldehydes and ketones using chirally modified cationic rhodium precatalysts results in reductive coupling to afford dienylated alpha-hydroxy heteroarenes 2-23 with exceptional levels of regio- and enantiocontrol. Coupling of enyne 1a to 2-pyridinecarboxaldehyde using an achiral rhodium catalyst in the presence of a chiral Akiyama-Terada-type phosphoric acid derived from BINOL as the Bronsted acid co-catalyst provides the coupling product 2 with substantial levels of optical enrichment (82% ee). This result suggests that substrate protonation and/or formation of a strong hydrogen bond occurs in advance of the stereogenic C-C bond forming event. Further, the high levels of asymmetric induction demonstrate that interaction of the aldehyde with the Bronsted acid activates the system toward C-C coupling. Reductive coupling of enyne 1a and 2-pyridinecarboxaldehyde under an atmosphere of elemental deuterium provides the monodeuterated product deuterio-2, consistent with a catalytic mechanism involving alkyne-carbonyl oxidative coupling followed by hydrogenolytic cleavage of the resulting oxametallacycle. The diene side chain of the coupling products is subject to diverse selective transformations, as demonstrated by the conversion of coupling products 2 and 8 to compounds 24-26 and 27-29, respectively.

An improved method for preparation of nitrile oxides from nitroalkanes for in situ dipolar cycloadditions

A new method has been found for generation of nitrile oxides in situ from nitroalkanes under mild conditions. Thus, reaction of nitroalkanes 1 with di-tert-butyl dicarbonate (2) and 4-dimethylaminopyridine (3) as catalyst in the presence of dipolarophiles at room temperature afforded cycloadducts (e.g. 5, 6, and 7) in improved yields compared to known methods. Solvent effects were also noted.

A strategic alternative to solid phase synthesis: Preparation of a small isoxazoline library by ‘fluorous synthesis’

The preparation of a highly fluorinated silyl group and its use as a ‘fluorous label’ are described. Allyl and propargyl alcohols are rendered fluorous upon attachment to the fluorous label. Cycloaddition of the fluorous dipolarophiles to nitrile oxides provides the corresponding isoxazol(in)es which are purified by simple liquid-liquid extractions. After detachment of the label and renewed extraction, the organic isoxazol(in)es are obtained. This new fluorous methodology allows the preparation of isoxazol(in)es in high purities without using chromatography.

Design, synthesis and crystallographic analysis of nitrile-based broad-spectrum peptidomimetic inhibitors for coronavirus 3C-like proteases

Coronaviral infection is associated with up to 5% of respiratory tract diseases. The 3C-like protease (3CLpro) of coronaviruses is required for proteolytic processing of polyproteins and viral replication, and is a promising target for the development of drugs against coronaviral infection. We designed and synthesized four nitrile-based peptidomimetic inhibitors with different N-terminal protective groups and different peptide length, and examined their inhibitory effect on the in-vitro enzymatic activity of 3CL pro of severe-acute-respiratory-syndrome-coronavirus. The IC 50 values of the inhibitors were in the range of 4.6-49 muM, demonstrating that the nitrile warhead can effectively inactivate the 3CL pro autocleavage process. The best inhibitor, Cbz-AVLQ-CN with an N-terminal carbobenzyloxy group, was ?10x more potent than the other inhibitors tested. Crystal structures of the enzyme-inhibitor complexes showed that the nitrile warhead inhibits 3CLpro by forming a covalent bond with the catalytic Cys145 residue, while the AVLQ peptide forms a number of favourable interactions with the S1-S4 substrate-binding pockets. We have further showed that the peptidomimetic inhibitor, Cbz-AVLQ-CN, has broad-spectrum inhibition against 3CLpro from human coronavirus strains 229E, NL63, OC43, HKU1, and infectious bronchitis virus, with IC 50 values ranging from 1.3 to 3.7 muM, but no detectable inhibition against caspase-3. In summary, we have shown that the nitrile-based peptidomimetic inhibitors are effective against 3CLpro, and they inhibit 3CLpro from a broad range of coronaviruses. Our results provide further insights into the future design of drugs that could serve as a first line defence against coronaviral infection.
