| titleOfInvention | Preparation method of maytansinoid and composition used in said method |
| abstract | The present invention provides efficient methods for the direct coupling of maytansinoids with carboxylic acids to prepare maytansinoid C-3 esters in high yields by using rare earth metal-based or triflate-based Lewis acid catalysts and a base together with A coupling reagent. Compositions for use in such methods are also provided. |
