Structure-Activity Relationships of Benzamides and Isoindolines Designed as SARS-CoV Protease Inhibitors Effective against SARS-CoV-2

Inhibition of coronavirus (CoV)-encoded papain-like cysteine proteases (PLpro) represents an attractive strategy to treat infections by these important human pathogens. Herein we report on structure-activity relationships (SAR) of the noncovalent active-site directed inhibitor (R)-5-amino-2-methyl-N-(1-(naphthalen-1-yl)ethyl) benzamide (2 b), which is known to bind into the S3 and S4 pockets of the SARS-CoV PLpro. Moreover, we report the discovery of isoindolines as a new class of potent PLpro inhibitors. The studies also provide a deeper understanding of the binding modes of this inhibitor class. Importantly, the inhibitors were also confirmed to inhibit SARS-CoV-2 replication in cell culture suggesting that, due to the high structural similarities of the target proteases, inhibitors identified against SARS-CoV PLpro are valuable starting points for the development of new pan-coronaviral inhibitors.

Selective catalytic Hofmann: N -alkylation of poor nucleophilic amines and amides with catalytic amounts of alkyl halides

Using only catalytic amounts of alkyl halides in the reactions of poor nucleophilic amines/amides and alcohols led to a selective Hofmann N-alkylation reaction catalytic in alkyl halides, providing a practical and efficient method for the practical synthesis of mono- or di-alkylated amines/amides in high selectivities. This new method avoids the use of large amounts of bases, alkyl halides, and solvents, and generates water as the only byproduct. Preliminary mechanistic studies showed that alkyl halides are key intermediates/catalysts regeneratable in the reaction cycle.

A facile access for the C-N bond formation by transition metal-free oxidative coupling of benzylic C-H bonds and amides

Using 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) as the oxidant, we communicate an efficient oxidative C-N coupling of benzylic C-H bonds with amides to afford a series of amination products in good yields. A wide range of functional groups as well as various sulfonamides and carboxamides are well tolerated. Moreover, this reaction involves both the challenging C-H functionalization and C-N bond formation.

Peroxidation of C-H bonds adjacent to an amide nitrogen atom under mild conditions

Under mild conditions, the oxidative functionalization of C-H bonds adjacent to an amide nitrogen atom was achieved. tert-Butylperoxyamido acetal was obtained in high yields and could be further converted into α-substituted amides by treatment with Grigna

HClO4-SiO2 as an efficient and recyclable catalyst for the synthesis of amide derivatives

An efficient and clean procedure for amide alkylation is reported by direct condensation of equimolar amounts of benzylic and allylic alcohols with primary amides in the presence of silica perchloric acid (HClO4-SiO 2). The direct co

o-Benzenedisulfonimide as a reusable Bronsted acid catalyst for Ritter-type reactions

Reactions between various benzyl alcohols or tert-butyl alcohol and nitriles were carried out in the presence of catalytic amounts (usually 10-20 mol-%) of o-benzenedisulfonimide as a Bronsted acid catalyst; the reaction conditions were mild and the yields of amides were good. The catalyst was easily recovered and purified, ready to be used in further reactions, with economic and ecological advantages. Wiley-VCH Verlag GmbH & Co. KGaA, 2009.

Polyvinylpolypyrrolidone-supported boron trifluoride: A high-loaded, polymer-supported Lewis acid for the Ritter reaction

A Mild and efficient method for preparing amides by reaction of nitriles with benzhydrol and tertiary alcohols is described using polyvinylpolypyrrolidone-supported boron trifluoride. Selective amidation of benzhydrol in the presence of primary benzyl alcohols was also achieved.
