For the first time we have been able to employ enantiopure 1,2‐aminoalcohols derived from abundant amino acids in C−C bond‐forming hydrogen‐borrowing alkylation reactions. These reactions are facilitated by the use of the aryl ketone Ph*COMe. Racemisation of the amine stereocentre during alkylation can be prevented by the use of sub‐stoichiometric base and protection of the nitrogen with a sterically

Disclosed are conjugates including a recognition element covalently bonded to or linked through a linker to a payload. The payload is a pharmaceutical agent (e.g., an antineoplastic agent, anti-infective agent, or anti-inflammatory agent) or a diagnostic agent. Also disclosed are methods of using the conjugates.
