标 题 :Synthesis of 1,3-oxathiolane sulfoxide compounds
发明人：MCPHEE DEREK JAMES
权利人:UNIROYAL CHEMICAL LTD
摘要:A process for the production of a 1,3-oxathiolane sulfoxide of the formula ##STR1## wherein X is an amino group of the formula --NHR, wherein R is hydrogen, phenyl, C 1 -C 8 alkyl, C 3 -C 6 cycloalkyl, nitrophenyl, (C 1 -C 4 alkoxy)phenyl, furfuryl, halophenyl, tolyl, napthyl, biphenyl or hydroxyphenyl; or X is an alkoxy group of the formula --OR 1 wherein R is C 1 -C 6 alkyl, n which process comprises oxidizing a 1,3-oxathiolane of the formula ##STR2## wherein X is as defined above, in the presence of an effective amount of aqueous hydrogen peroxide and a sterically-hindered organoselenium compound of the formula ##STR3## wherein R 2 is aryl, mono-, di- or tri-substituted with C 1 -C 3 alkyl, n to the produce the 1,3-oxathiolane sulfoxide. This process stereoselectively produces the cis stereoisomer of the 1,3-oxathiolane sulfoxide. Additionally, there is disclosed a novel method for the preparation of 5,6-dihydro-2-methyl-1,4-oxathiin compounds using this process.
