and Oxidatively Cleavable Tritylthio and (4-Methoxytrityl)thio Groups. — The
new protecting groups -Mob and -Tab are designed, which can be easily introduced at
the 5'-OH function of deoxynucleosides such as (I). They are removable by intramolecular cyclization following oxidative hydrolysis of the tritylthio-type substituents under mild conditions. — (SEIO, K.; UTAGAWA, E.; SEKINE*, M.; Helv. Chim. Acta
