SYNTHESIS AND STRUCTURE OF NEW DERIVATIVES OF THIENO[2,3-B]THIOCINE -UNUSUAL INTRAMOLECULAR CYCLOADDITION PRODUCT OF 2-HOMOMETHALLYL-3-THIOPHENECARBONITRILE OXIDE
Mm. Krayushkin et al., SYNTHESIS AND STRUCTURE OF NEW DERIVATIVES OF THIENO[2,3-B]THIOCINE -UNUSUAL INTRAMOLECULAR CYCLOADDITION PRODUCT OF 2-HOMOMETHALLYL-3-THIOPHENECARBONITRILE OXIDE, Mendeleev communications, (3), 1993, pp. 114-115
For the first time 5,6-hexahydrothieno[2,3-b]thiocine[4,5-c]isoxazole
and o-3,4,6-hexahydro-5-methylenethieno[2,3-b]thiocine have been prepa
red by NaOCl oxidation of 2-omega-alkenylthio-3-thiophenecarbal-doxime
s. The structure of these products has been confirmed by mass, H-1 NMR
and C-13 NMR spectroscopy, and of the second, also by X-ray analysis.
