A characteristic red pyrrolizin-3-one (coloured tag) is then revealed on treatment with hydrocinnamoyl chloride. This sequence has been carried out on amino acids in solution, and on solid phase, and also on dipeptides. A method is presented whereby an amino acid is reacted with 5-formyl-1H-pyrrole-2-carboxylic acid to give an N-derivatised tag that has a latent ability to be coloured.158746 bytesapplication/pdfenJournal article002006510910.1016/S0040-4039(02)00625-10001755553000162-s2.0-003707119849935Abell, A.
