Résumé
A novel type of photodeprotection reaction of simple arom. acetals and ketals is described. The deprotection is highly efficient under optimized conditions. The arom. ring confers the photoreactivity to the compds. The efficiency of the process depends on the structure of the acetal moiety. The common minor side reaction, the photooxidn., becomes the major reaction pathway in the case of cyclic acetals. The use of photon as only reagent makes this procedure esp. attractive for acetal deprotection. [on SciFinder(R)]
