Abstract

The properties of three oxobenzo [f] benzopyrans as new fluorogenic photolabile protecting groups for the carboxylic function of amino acids were studied. Fluorescent amino acid conjugates were efficiently prepared and characterised. Photodeprotection of these compounds was carried out by irradiation at 300, 350 and 419nm, the most suitable wavelength being 350nm, on account of short irradiation times and good deprotection ...
