Organocatalytic asymmetric total synthesis of (R)-rolipram and formal synthesis of (3S,4R)-paroxetine.

ABSTRACT

An efficient enantioselective total synthesis of (R)-rolipram and an efficient enantioselective formal synthesis of (3S,4R)-paroxetine has been achieved using the highly enantioselective Michael addition of malonate nucleophiles as key steps in both cases.
