| N-叔丁氧羰基-L-亮氨醇 | (S)-(1-hydroxymethyl-3-methylbutyl)carbamic acid tert-butyl ester | 82010-31-9 | C11H23NO3 | 217.309 |
An alternative route to obtain Ψ(CH2O) pseudodipeptide unit based on insertion of carbens in hydroxylic bond of alcohols mediated by catalyst rhodium(II) acetate is described. In that way, N-protected derivatives of alaninol, valinol, isoleucinol leucinol and phenylalaninol were converted, upon a treatment with methyl or ethyl diazoacetate, to corresponding fully protected pseudodipeptides with methyleneoxy isostere bond which can be further used in peptide synthesis.
