In control: The novel and enantioselective total synthesis of (-)-quinocarcin includes the highly stereoselective preparation of the 2,5-cis-pyrrolidine by intramolecular amination, a selective substrate-controlled 6-endo-dig intramolecular alkyne hydroamination with a cationic Au(I) catalyst, and Lewis-acid-mediated ring-opening/halogenation sequence.

Novel dispirooxindole-pyrrolidine derivatives have been synthesized through 1,3-dipolar cycloaddition of an azomethine ylide generated from isatin and sarcosine with the dipolarophile 3-(1H-indol-3-yl)-3-oxo-2-(2-oxoindolin-3-ylidene)propanenitrile, and also spiro compound of acenaphthenequinone obtained by the same optimized reaction condition. Synthesized compounds were evaluated for

The nitroxides of 7-azadispiro[5.1.5.2]pentadecane and 7-azadispiro[5.1.5.2]pentadeca-14-ene series have been prepared, including thiol-specific methane thiosulfonate spin label for site-directed spin labeling. The effect of spirocyclohexane moieties on chemical and spectral properties has been studied. The obtained temperature dependencies of electron spin

We have synthesized and characterized a series of compounds containing the 3-azatetracyclo[5.2.1.1(5,8).0(1,5)]undecane scaffold designed as analogues of amantadine, an inhibitor of the M2 proton channel of influenza A virus. Inhibition of the wild-type (WT) M2 channel and the amantadine-resistant A/M2-S31N
