To create highly efficient inhibitors for FK506‐binding proteins, a new asymmetric synthesis for pro‐(S)‐C5‐branched [4.3.1] aza‐amide bicycles was developed. The key step of the synthesis is an HF‐driven N‐acyliminium cyclization. Functionalization of the C5 moiety resulted in novel protein contacts with the psychiatric risk factor FKBP51, which led to a more than 280‐fold enhancement in affinity
