M. Belyk, David M. TschaenThe development of
a concise asymmetric synthesis of the antiviral
development candidate letermovir is reported, proceeding in >60%
yield
over a total of seven steps from commercially available materials.
Key to the effectiveness of this process is a novel cinchonidine-based
PTC-catalyzed aza-Michael reaction to configure the single stereocenter.
