Crystal and Molecular Structure and Spectra of 2',2',5,5,5',5',7,7-Octamethyl-2',5,5',7-tetrahydrofuro-1-oxa-3,4-diselenin-2-spiro-3'-furan-4'(3'H)-one from Selenium Dioxide Oxidation of 2,2,5,5-Tetramethyltetrahydrofuran-3-one. A Novel Six-membered Heterocyclic Ring System in ...

When 2,2,5,5-tetramethyltetrahydrofuran-3-one 1 was oxidized with selenium dioxide in ethanol, the title heterocycle 4 was formed along with 2,2,5,5-tetramethyltetrahydro-3,4-furandione 2.The diselenide 4 represents a novel six-membered heterocycle in the chalcogen series.

SYNTHESIS AND STRUCTURE OF E,Z-ISOMERIC FIVE-MEMBERED CYCLIC α-KETO-N-METHYL NITRONES

The respective E-isomeric nitrones were obtained by methylation of the monooximes of cyclic α-diketones.The photochemical transformation of five-membered cyclic E-α-keto-N-methyl nitrones into the thermodynamically less stable Z isomers was realized for the first time, and the conditions for the preparative realization of the process were determined.Detailed investigation of the IR, UV, PMR and 13C NMR spectra and the dipole moments of the obtained nitrones showed that the dipole moments and PMR spectra are most suitable for determinig the configuration (E or Z).
