First claim
Opening claim text (preview).
The invention claimed is: 1. A composition comprising an enantiomerically pure β-lactam having an N-Tr moiety, wherein the nitrogen of said N-Tr moiety is covalently bonded to two of the carbons of the four-atom ring structure wherein the enantiomerically pure β-lactam consists essentially of one of the following: 2. A composition comprising an enantiomerically pure β-lactam wherein the enantiomerically pure β-lactam consists of compound 34 as shown below: 3. The composition of claim 1 wherein the enantiomerically pure β-lactam consists essentially of Compound 10. 4. The composition of claim 1 wherein the enantiomerically pure β-lactam consists essentially of Compound 11. 5. The composition of claim 1 wherein the enantiomerically pure β-lactam consists essentially of Compound 15. 6. The composition of claim 1 wherein the enantiomerically pure β-lactam consists essentially of Compound 16. 7. The composition of claim 1 wherein the enantiomerically pure β-lactam consists essentially of Compound 17. 8. The composition of claim 1 wherein the enantiomerically pure β-lactam consists essentially of Compound 23. 9. The composition of claim 1 wherein the enantiomerically pure β-lactam consists essentially of Compound 26. 10. The composition of claim 1 wherein the enantiomerically pure β-lactam consists essentially of Compound 27. 11. The composition of claim 1 wherein the enantiomerically pure β-lactam consists essentially of Compound 28. 12. The composition of claim 1 wherein the enantiomerically pure β-lactam consists essentially of Compound 29. 13. The composition of claim 1 wherein the enantiomerically pure β-lactam consists essentially of Compound 30. 14. The composition of claim 1 wherein the enantiomerically pure β-lactam consists essentially of Compound 31. 15. The composition of claim 1 wherein the enantiomerically pure β-lactam consists essentially of Compound 32. 16. The composition of claim 1 wherein the enantiomerically pure β-lactam consists essentially of Compound 34.
