PROTECTION DES PHENOLS PAR LE GROUPEMENT AZIDOMETHYLENE APPLICATION A LA SYNTHESE DE PHENOLS INSTABLES

Loubinoux, Bernard,Tabbache, Samir,Gerardin, Philippe,Miazimbakana, Joseph

, p. 6055 - 6064 (2007/10/02)

Phenols are protected by the azidomethylene group in basic, nucleophilic, oxidative, weakly reductive and weakly acidic media.This group is obtained by the reaction of sodium azide with aryloxymethyl chlorides.Its utility lies in the ease with which it can be removed under very mild conditions which allows the synthesis of very unstable phenolic compounds.
