| titleOfInvention |
Thiazolinoazetidinone derivative and process for preparing 2-exo-methylene-penam derivative thereform |
| abstract |
The present invention provides a thiazolinoazetidinone derivative represented by the formulan n wherein R¹ is phenyl having or not having substituent(s), methyl having or not having substituent(s) orn n group, R³ being phenyl having or not having substituent(s), and R² is a hydrogen atom or carboxylic acid protective group, and a process for preparing the same. n The present invention further provides a process for preparing a 2-exo-methylenepenam derivative characterized by hydrolyzing the thiazoline ring of a thiazolinoazetidinone derivative of the above formula (1) to effect recyclization and obtain a 2-exo-methylenepenam derivative represented by the formulan n wherein R¹ and R² are as defined above. |
