A Fe(III)-catalyzed N-amidomethylation of secondary and primary anilines with p-toluenesulfonylmethyl isocyanide (TosMIC) in water was described. TosMIC played dual roles as the source of methylene as well as an amidating reagent to form α-amino amides R1N(R2)CH2C(O)NHR3 [R1 = Ph, 2-MeC6H4, 4-FC6H4, etc.; R2 = H, Me, Bn, etc.; R3 = t-Bu, 4-MeC6H4SO2CH2, 4-ClC6H4SO2CH2] in this multicomponent reaction. The combination of TosMIC and other isocyanides was also investigated to give the desired products in acceptable yields. The current protocol features used of iron catalyst and nontoxic media, broad substrate scope, mild conditions and operational simplicity.

Zhang, Xujie published the artcileDesign, synthesis, and mechanism study of dimerized phenylalanine derivatives as novel HIV-1 capsid inhibitors, Recommanded Product: 4-Methoxy-N-methylaniline, the main research area is design synthesis mechanism study dimerized phenylalanine; HIV1 capside inhibitor phenylalanine dimer structure activity relationship; Assembly; Capsid; Dimer; HIV-1; Phenylalanine derivatives.

HIV-1 capsid (CA) plays indispensable and multiple roles in the life cycle of HIV-1, become an attractive target in antiviral therapy. Herein, we report the design, synthesis, and mechanism study of a novel series of dimerized phenylalanine derivatives as HIV-1 capsid inhibitors using 2-piperazineone or 2,5-piperazinedione as a linker. The structure-activity relationship (SAR) indicated that dimerized phenylalanines were more potent than monomers of the same chemotype. Further, the inclusion of fluorine substituted phenylalanine and methoxyl substituted aniline was found to be beneficial for antiviral activity. From the synthesized series, I was found to be the most potent compound with an EC50 value of 0.57μM, comparable to II. Interestingly, I demonstrated a slightly higher affinity to the CA monomer than the CA hexamer, commensurate with its more significant effect in the late-stage of the HIV-1 lifecycle. Competitive SPR experiments with peptides from CPSF6 and NUP153 revealed that Q-c4 binds to the interprotomer pocket of hexameric CA as designed. Single-round infection assays showed that I interferes with the HIV-1 life cycle in a dual-stage manner, affecting both pre-and post-integration. Stability assays in human plasma and human liver microsomes indicated that although I has improved stability over II, this kind of inhibitor still requires further optimization. And the results of the online molinspiration software predicted that I has desirable physicochem. properties but some properties still have some violation from the Lipinski rule of five. Overall, the dimerized phenylalanines are promising novel platforms for developing future HIV-1 CA inhibitors with considerable potential for optimization.

Li, Zhen published the artcileThermodynamic and kinetic studies of hydride transfer from Hantzsch ester under the promotion of organic bases, Related Products of isoquinoline, the main research area is hydride transfer kinetics thermodn Hantzsch ester promotion organic base.

Base-promoted hydride transfer (BPHyT), a strategy for the upconversion of hydride donors, was studied here in a three-component system, composed of Hantzsch ester (HEH), acridinium derivatives and organic bases. Based on the thermodn. parameters of hydricity and pKa, we proposed a thermodn. cycle to evaluate the apparent hydricity of HEH/base combinations, as well as the overall driving force of BPHyT. Bronsted-type linear anal. indicated that the base used in BPHyT is much more effective to regulate the reaction kinetics, compared to conventional Bronsted acid or base catalysis. Structure-reactivity relationships showed that the hydride acceptor and the base contribute equally to regulate the kinetics of BPHyT. Kinetic isotope effects suggested that the hydride transfer is involved in the rate-determining step. Reductions of the polar C:C bonds by HEH/base combinations were performed to confirm the feasibility of applying BPHyT in organic synthesis.
