Definitions
- the invention relates to processes for the production of epothilones and intermediates within the process.
- Epothilone 1 (DE 41 38 042 C2) represent a new class of tubulin-stabilizing natural products with T.axol-like activity. Their cytotoxic activity against drug-resistant tumor cell lines is of enormous importance for potential use in cancer therapy [G. Höfle , N. Bedorf, H. Steinmetz, D. Schomburg, K. Gerth, H.
