degradation: A highly enantio‐ and diastereoselective guanidine‐catalyzed Mannich reaction was developed with α‐fluoro‐β‐keto acyloxazolidinone as the fluorocarbon nucleophile (see scheme). α‐Fluoro‐β‐amino ester and α‐fluoro‐β‐amino ketones with chiral fluorinated carbon were obtained by selective deacylation and decarboxylation reactions, respectively.
