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 419 nm, the most suitable wavelength being 350 nm, on account of short irradiation times
研究了三个氧代苯并[ f ]苯并吡喃类作为新的对氨基酸的羧基官能团的光不稳定保护基的性质。荧光氨基酸缀合物得到了有效的制备和表征。这些化合物的光脱保护是通过在300、350和419 nm处进行辐照进行的,最短的辐照时间和良好的脱保护收率是最合适的波长是350 nm。
