The synthesis and photochemistry of functionalized 3-aroyl-2-(2-furyl)-chromones1 which are photoactivable fluorophores are described. Irradiation converts the non-fluorescent furyl chromones to highly fluorescent 1-arylfuro[3,4b]chromones3. Functionality has been incorporated to permit covalent attachment, impart aqueous solubility and to maximize the fluorescence of the ultimate 1-arylfuro[3,4b]chromone
描述了作为可光活化的荧光团的官能化的3-芳酰基-2-(2-呋喃基)-色酮1的合成和光化学。辐射将非荧光呋喃基色酮转化为高荧光的1-芳基呋喃[3,4b]色酮3。引入了功能以允许共价连接,赋予水溶性并最大程度地提高最终的1-芳基呋喃[3,4b]色酮荧光团的荧光。还描述了通过分子内Dieckman环化到呋喃基色酮的有效合成途径。
