The carboxylic acid group on the proline of 1 was replaced by a phosphoric acid, a hydroxamic acid, and a tetrazole to give compounds 2-4, respectively. Testing of 2-4 as angiotensin converting enzyme (ACE) inhibitors gave I50 values of 100, 1.6, and 22 microM, respectively, compared to 0.07 microM for 1. A hydroxamic acid derivative of the ketomethylene pentapeptide analogue 18 was then synthesized

The alkylation reaction of diethyl N-(diphenylmethylene)aminomethylphosphonate (6) with alkyldihalides under phase-transfer catalysis followed by hydrolysis of the benzophenone imine moiety and subsequent cyclization provides a simple and convenient method for the synthesis of known and new cyclic α-aminophosphonates 1–5 in moderate to good yields.

Unprotected alicyclic amines undergo α-C–H bond phosphonylation via a two-stage one-pot process involving the oxidation of amine-derived lithium amides with simple ketone oxidants, generating transient imines which are then captured with phosphites or phosphine oxides. Amines with an existing α-substituent undergo regioselective α′-phosphonylation. Amine α-arylation and α′-phosphonylation can be combined
