The anion of t-butyl-N-hydroxycarbamate displaces halogens from (eta-6-haloarene) (eta-5-cyclopentadienyliron) salts. The resulting complexes are demetallated by photolysis in sunlight to generate t-butyl-N-(aryloxy)carbamates.
Peptides with an N-alkoxy or N-aryloxy amino acid at their N-terminus were synthesized and successfully ligated with a peptidethioester by silver ion activation under a slightly acidic condition without requiring protection of the side chain amino groups. The N-methoxy group was easily cleaved by the SmI2 reduction in CH3OH aq. to obtain the desired peptide with a native peptide bond. This method
