Rapid Access to Tricyclic Ring
System Containing Isoindolone by Novel Diastereoselective
Intramolecular Aldol-Type Cyclization of N-Substituted Phthalimides
Carbapenem derivatives which may be utilized as antibiotics and which show strong antibacterial activity against various bacterial strains including Pseudomonas aeruginosa. The compounds containing the derivatives are quite safe and are also stable against hydrolases such as dehyropeptidase (DHP).

System Containing Isoindolone by Novel Diastereoselective
Intramolecular Aldol-Type Cyclization of N-Substituted Phthalimides
The cyclization of N-substituted phthalimide to 3-hydroxyisoindolone derivatives has been successfully carried out by the base-promoted aldol-type reaction. The new morpholine and thiomorpholine derivatives have been synthesized and characterized.
