title: A bifunctional spiro-type organocatalyst with high enantiocontrol: application to the aza-Morita-Baylis-Hillman reactions.
abstract: A unique spiro-type Brønsted acid-Lewis base organocatalyst has been developed. The new bifunctional organocatalyst promoted aza-Morita-Baylis-Hillman reactions to yield adducts with up to 98% ee.
