Structural modifications of salicylates: Inhibitors of human CD81-receptor HCV-E2 interaction

Starting point of the present paper was the result of a virtual screening using the open conformation of the large extracellular loop (LEL) of the CD81-receptor (crystal structure: PDB-ID: 1G8Q). After benzyl salicylate had been experimentally validated to be a moderate inhibitor of the CD81-LEL-HCV-E2 interaction, further optimization was performed and heterocyclic-substituted benzyl salicylate derivatives were synthesized. The compounds were tested for their ability to inhibit the interaction of a fluorescence-labeled antibody to CD81-LEL using HUH7.5 cells. No compound showed an increase concerning the inhibition of the protein-protein interaction compared to benzyl salicylate.

Transition-Metal-Free N-Arylation of Amines by Triarylsulfonium Triflates

A simple and efficient method for transition-metal-free N-arylation of various amines by triarylsulfonium triflates is described. Both aliphatic and aromatic amines were smoothly converted at 80 C in the presence of tBuOK or KOH to give the corresponding mono N-arylated products in good to high yields. The molar ratios of the reactants and the choice of bases had a big effect on the reaction. When a large excess of [Ph3S][OTf] and tBuOK were employed for primary amines under the standard conditions, the bis(N-phenyl) products were predominantly formed. This method was also applicable to the synthesis of bioactive N-phenyl amino acid derivatives. The control experiments, the deuterium labelling study, and the presence of regioisomers of N-arylated products when using 4-substituted triarylsulfonium triflates suggested that the reaction might proceed through an aryne intermediate. The present protocol demonstrated that triarylsulfonium salts are versatile arylation reagents in the construction of CAr?N bonds.

Copper-catalyzed aerobic cyclizations of tetrahydroisoquinolines with bromoketones and alkenes for the synthesis of 5,6-dihydropyrrolo[2,1-a] isoquinolines

A new copper-catalyzed oxidative cyclization protocol was developed for the synthesis of 5,6-dihydropyrrolo[2,1-a]isoquinolines via a three-component reaction of tetrahydroisoquinolines with bromoketones and electron-deficient alkenes with air as a terminal oxidant. A variety of functional groups survived under the reaction conditions and the target products were obtained in good yields. This reaction features such advantages as eco-friendly reaction conditions, a simplified operation process and a broad substrate scope.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application In Synthesis of 6-Bromo-1,2,3,4-tetrahydroisoquinoline, you can also check out more blogs about226942-29-6

Unique regioselectivity in the C(sp3)-H alpha-alkylation of amines: The benzoxazole moiety as a removable directing group

The benzoxazol-2-yl- substituent was found to act as a removable activating and directing group in the Ir-catalyzed alkylation of C(sp3)-H bonds adjacent to nitrogen in secondary amines. It can be easily introduced by oxidative coupling or by an SNAr reaction, and it can be removed by hydroxide or by hydride reduction. For 1,2,3,4-tetrahydroisoquinolines, activation exclusively takes place in the 3-position. A variety of activated as well as unactivated terminal olefins are suitable reaction partners.

Direct ester condensation from a 1:1 mixture of carboxylic acids and alcohols catalyzed by hafnium(IV) or zirconium(IV) salts

To promote atom efficiency in synthesis and to avoid the generation of environmental waste, the use of stoichiometric amounts of condensing reagents or excess substrates should be avoided. In esterification, excess amounts of either carboxylic acids or alcohols are normally needed. We found that the direct condensation of equimolar amounts of carboxylic acids and alcohols could be achieved using hafnium(IV) or zirconium(IV) salts. These metal salts are highly effective as catalysts for the selective esterification of primary alcohols with carboxylic acids in the presence of secondary alcohols or aromatic alcohols. The present methods can be applied to direct polyesterification and may be suitable for large-scale operations.

New catalytic effect of thiourea on the oxidative cyanation of N-aryltetrahydroisoquinolines

Thiourea itself has been introduced as a mild and efficient organocatalyst for the oxidative alpha -cyanation of N-aryltetrahydroisoquinolines (THIQs) with trimethylsilyl cyanide (TMSCN), giving the corresponding products in good to excellent yields. Experimental investigations demonstrated that thiourea acts as a radical initiator by abstracting hydroxyl radical ([rad]OH) from tert-butyl hydroperoxide (TBHP) directly instead of non-covalent hydrogen bondings (H-bondings) activation. The use of thiourea as a radical initiator offers a new avenue for innovative chemical transformations in organocatalyzed radical chemistry.
