Enantioselective Iridium-Catalyzed
Allylic Aminations of Allylic Carbonates with Functionalized Side
Chains. Asymmetric Total Synthesis of (<i>S</i>)-Vigabatrin
Iridium-catalyzedaminations of allylic carbonates containing a variety of O-functional groups have been explored. High degrees of regio- as well as enantioselectivity were achieved with diacylamides under salt-free conditions and with arylamines. The results allowed the antiepilepsy drug (S)-vigabatrin to be prepared via a very short route.
