Abstract:

ABSTRACT Enterovirus 71 is one of the most important pathogens in the family of Picornaviridae that can cause severe complications in the postpoliovirus era, such as encephalitis, pulmonary edema, and even death. Pyridyl imidazolidinone is a novel class of potent and selective human enterovirus 71 inhibitor. Pyridyl imidazolidinone was identified by using computer-assisted drug design. This virologic investigation demonstrates that BPR0Z-194, one of the pyridyl imidazolidinones, targets enterovirus 71 capsid protein VP1. Time course experiments revealed that BPR0Z-194 effectively inhibited vir

Abstract:

The attempted synthesis of a β-keto imidazolidinone nitroxide by oxidation of the β-hydroxy imidazolidinone precursor with hydrogen peroxide and sodium tungstate led to an unexpected ring-opening reaction to produce 1,4-diazaspiro[4.5]dec-1-en-3-oxo-2-pentanoic acid 1-oxide (13) in high yield. The structure of 13 was confirmed by X-ray crystallographic analysis. A β-fragmentation mechanism is suggested for the oxidative ring-opening reaction.

Abstract:

Within this study, we report a simple two-step process for the synthesis of perfluoroalkylated pyrazoles from aliphatic aldehydes. In the photocatalytic first step, the aldehydes are transformed into the corresponding perfluoroalkylated enals, which then undergo nucleophilic attack by hydrazine and subsequent ring closure, providing the fluorinated 3,4-substituted pyrazole products in a 64–84% yield. Using triphenylphosphine and imidazolidinone as organocatalysts, the method is operationally simple and omits heavy metal-containing waste.

Abstract:

Efficient conditions have been developed for the diastereoselective aziridination of the biomass pyrolysis product (−)-levoglucosenone, via the reaction of primary aliphatic amines with 3-iodolevoglucosenone. In contrast to the reactions of aliphatic amines, the use of 4-methoxyaniline resulted in an aza-Michael-initiated dimerisation reaction, and 1,3-diphenylurea gave a 2-imidazolidinone. The aziridine products were transformed using the aza-Wharton reaction, affording novel sulfonamide and amine-substituted 6,8-dioxabicyclo[3.2.1]oct-3-enes with potential as sp3-rich chiral scaffolds.
