    • For the corresponding enzyme (oxynitrilase) mechanism, it was found that the addition step of the nucleophile on the aldehyde carbonyl is the rate-determining step (see: Ching, W.-M.; Kallen, R. G. J. Am. Chem. Soc. 1978, 100, 6119-6124). This seems to be the case in the catalysis by dipeptide 1 also, since electron-poor aldehydes are reported to react in shorter reaction times than their electron-rich counterparts (compare Figure 13).
