Stereoselective process and crystalline forms of a camptothecin |
| abstract |
A stereoselective process for preparing 7-[(E)-t-butyloxyiminomethyl]-camptothecin (also known as gimatecan) is herein disclosed. With the addition of further dissolution and precipitation steps carried out in appropriate different solvent mixtures, four new crystalline forms of gimatecan are also obtainable by using the same stereoselective process. |
