The reaction of ninhydrin with an -amino acid occurs in several steps (a) The first step is loss of water to give a triketone. Show the mechanism of the reaction and the structure of the triketone.(b) The second step is formation of an imine by reaction of the amino acid with the triketone. Show its structure. (c) The third step is a decarboxylation. Show the structure of the product and the mechanism of the decarboxylation reaction. (d) The fourth step is hydrolysis of an imine to yield an amine and an aldehyde. Show the structures of both products. (e) The final step is formation of the purple anion. Show the mechanism of the reaction
tert-Butoxycarbonyl azide was developed as a reagent for peptide synthesis at OWL's home institution, the University of Massachusetts, by Prof. L.A. Carpino. It is prepared by treating tert-butoxycarbonyl chloride with sodium azide. Propose a structure for the initially-formed intermediate in this reaction.
