titleOfInvention | Process for selective derivatization of taxanes |
abstract | A process is described for converting the C(7) hydroxy group of a 10-acyloxy-7-hydroxytaxane to an acetal or ketal, the process comprising treating the 10-acyloxy-7-hydroxytaxane with a ketalizing agent in the presence of an acid catalyst to form a C(7) ketalized taxane of the formula or wherein either X<sup>31</sup> or X<sup>32</sup> represents the 10-acyloxy-7-hydroxytaxane moiety and the other of X<sup>31</sup> and X<sup>32</sup> as well as X<sup>33</sup> and X<sup>34</sup> are independently hydrocarbyl, substituted hydrocarbyl or heteroaryl moieties. Taxanes having a ketalized C(7) hydroxy group are also described. |
