Synthesis of taxoids I. Regioselective Lewis acid-mediated ring-opening of aryl orthoacetates

The reaction of aryl orthoacetates with acetyl bromide readily proceeded regioselectively to afford the desirable aryl bromides in the presence of tin(II) or zinc bromide as a catalyst. The synthesis of some docetaxel derivatives is also described by using this improved process.
