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

Drop it! A highly enantioselective catalytic cascade reaction of α-ketoacids and aldehydes is achieved using the title catalyst and water as the solvent. Fluorescence imaging shows that the catalyst is mainly distributed on the surface of emulsion droplets. Optically active

We report an enantioselective synthesis of the polyhydroxylated pyrrolidine alkaloid (+)-DMDP. The key steps in the synthesis were guanidinium ylide mediated asymmetric aziridination, stereospecific ring opening of trans-3-vinylaziridine-2-carboxylate with an oxygen nucleophile, iodine-mediated 5-endo-trig amino cyclization, and Prévost displacement.

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
