Abstract
A novel photolabile protecting group, thiochromone S,S-dioxide, containing the diazomethyl group for protection of phosphate derivatives is described. Deprotection of the successfully protected phosphate derivatives proceeded smoothly under photoirradiation using an ultrahigh-pressure mercury lamp to recover the corresponding phosphates quantitatively, and the photoproduct derived from the thiochromone derivative showed high fluorescence intensity.
