Four diastereomers of a Phe-Ala peptide mimic incorporating a central silanediol group have been individually prepared and tested as inhibitors of angiotensin-converting enzyme (ACE). Three of the silanediols exhibit levels of inhibition that are similar to those of corresponding ketones reported by Almquist. For the fourth diastereomer, with both stereogenic carbons inverted relative to the most active isomer, the ketone gives the least enzyme inhibition whereas the silanediol shows a surprisingly low IC50 value.

Silanediol Inhibitors of Angiotensin-Converting Enzyme. Synthesis and Evaluation of Four Diastereomers of Phe[Si]Ala Dipeptide Analogues<sup>1</sup>
Four stereoisomers of a Phe-Ala silanediol dipeptide mimic have been evaluated as inhibitors of angiotensin-converting enzyme (ACE) and compared to ketone-based inhibitors reported by Almquist et al. One stereogenic center of the isomers was derived from the individual enantiomers of methyl 3-hydroxy-2-methylpropionate, with separation of diastereomers after introduction of the second stereogenic center
