Abstract: | 9-Methyl-3,3a,4,5-tetrahydro-6H-thieno2,3-b]thiocino4,5-c]isoxazole and 9-hydroxyimino-2-methyl-7-methylene-6, 7,8,9-tetrahydro-5H-thieno2,3-b]thiocine have been prepared for the first time by the oxidation of 2- -alkenylthio-3-thiophenecarbaldoximes with NaOCl. X-ray structural investigations of thieno2,3-b]thiocine and 2-homomethallylthio-5-methyl-3-thiophenecarbaldoxime have been carried out.Translated fromIzvestiya Akademii Nauk.
