A highly diastereoselective [3 + 2] cycloaddition of aziridines with difluorinated silyl enol ethers has been developed. This approach provides a facile methodology for functionalized gem-difluorinated pyrrolidines in good to excellent yields functional group tolerance. one-pot, two-step synthesis structurally interesting fluorinated pyrroles also developed through cycloaddition/aromatization/desulfonation sequence. Moreover, readily available substrates, mild reaction conditions, and easy scale-up show practical advantages.

Human immunodeficiency virus (HIV) especially HIV-1 infection and its progression to acquired immune deficiency syndrome (AIDS) remains a significant global health challenge. The advent of the highly active antiretroviral therapy (HAART) has greatly extended life expectancy patients living with HIV, but it become evident that long-term HAART will not eliminate HIV reservoir cure infection. Moreover, drug resistance undesirable side effects hamper efficacious therapy, creating an urgent need develop novel, more effective less toxic anti-HIV therapeutics. Imidazole, oxazole thiazole two heteroatoms at meta-position five-membered rings are fascinating structures constitute important class heterocycles in discovery. Their derivatives could exert activity through diverse mechanisms possess promising antiviral against both drug-sensitive drug-resistant strains. This review summarizes research progress made regarding potential imidazole, hybrids, structure–activity relationships (SARs) also discussed facilitate further rational design candidates, covering articles published from 2012 2022.

Histone-modifying enzymes are the key regulators involved in post-translational modification of histone and non-histone. These responsible for epigenetic control cellular functions. However, deregulation activity these results uncontrolled disorders such as cancer inflammatory neurological diseases. The study includes acetyltransferases, deacetylases, methyl transferases, demethylases, DNA their potent inhibitors which a clinical trial used medicinal drugs. present review covers heterocycles target-specific histone-modifying enzyme, more specifically acetyltransferases. This also confers recent reports on potential HAT covered from 2016 to 2022 future perspectives therapy.

A concise asymmetric total synthesis of (-)-quinocarcin has been accomplished with high step economy from commercially available starting materials. catalytic enantioselective reductive 1,3-dipolar cycloaddition reaction N-heteroaryl secondary amides reactive dipolarophiles using iridium/copper relay catalysis was developed to prepare the key chiral pyrrolidine intermediate three stereocenters. This protocol features excellent regio-, exo- and enantioselectivities, broad substrate scope, good functional group tolerance. The efficiency also ensured by a RhIII -catalyzed C-H activation/cyclization tandem diastereoselective hydrogenation/cyclization construct tetrahydroisoquinoline-pyrrolidine tetracyclic core unit quinocarcin.
