2-(Azidomethyl)benzoyl as a new protecting group in nucleosides
Wada, Takeshi,Ohkubo, Akihiro,Mochizuki, Akira,Sekine, Mitsuo
, p. 1069 - 1072 (2001)
A new protecting group, 2-(azidomethyl)benzoyl (AZMB), which can be easily removed by treatment with MePPh2 in dioxane-H2O or reduction with HCOONH4-Pd/C in dioxane-MeOH, was developed for protection of the hydroxy and amino functions of deoxyribonucleosides.
