| titleOfInvention | Process for preparation of 4-sulfonylthio azetidinone derivatives |
| abstract | A process for preparing an azetidinone derivative represented by the formula <IMAGE> (I) wherein R1 is hydrogen, halogen or lower alkoxy, R2 is hydrogen, halogen, lower alkoxy, amino or a group <IMAGE> (in which R5 is substituted or unsubstituted phenyl, substituted or unsubstituted phenylmethyl, substituted or unsubstituted phenoxymethyl, or substituted or unsubstituted benzoyl), or R1 and R2, when taken together, are carbonyl, R3 is substituted or unsubstituted phenyl, and R4 is hydrogen, optionally substituted hydrocarbon residue or acyl, silyl, sulfonyl or phosphonyl derived from inorganic acid or organic acid, the process comprising reacting a dithioazetidinone derivative represented by the formula <IMAGE> (VI) wherein R1, R2 and R4 are as defined above and R9 is substituted or unsubstituted, nitrogen-containing aromatic heterocyclic residue with a compound represented by the formula R3SO2SR9 (VII) wherein R3 and R9 are as defined above. |
