✦ Synopsis


The new C2-symmetrical ferrocenyl amines 2 and 3 are easily prepared starting from the ketones 4. Their utility is demonstrated for enantioselective deprotonation reactions and highly diastereoselective alkylations of the amides 7.

## Abstract Enantiopure N‐sulfinyl‐δ‐amino‐β‐ketoesters and isoquinolones, prepared from sulfinimines (N‐sulfinyl imines) are a new class of polyfunctionalized chiral building blocks. These building blocks provide easy access to enantiomerically pure, functionalized piperidines and tetrahydroisoqui
