Methods for the synthesis of CCI-779 and proline-CCI-779 are described, including a method involving lipase-catalyzed acetylation of 42-hydroxy of rapamycin with a vinyl ester of 2,2-bis(hydroxymethyl) propionic acid in an organic solvent followed by deprotection. Also provided are products containing proline-CCI-779 and uses thereof.
