چکیده انگلیسی
An efficient, chemoselective and eco-friendly protocol for the protection of amines as N-tert-butylcarbamate using (Boc)2O and protection of alcohols as silyl ether using HMDS over tungstophosphoric acid/SBA15 has been developed. Solventless condition, easy work-up, short reaction time, excellent yields and reusability of the catalyst are the striking features of this methodology which can be considered to be one of the better methods for the protection of amines and alcohols.
A green method has been adopted for the protection of amines as N-Boc and alcohols as silyl ether in the presence of tungstophosphoric acid-doped mesoporous silica (SBA15).
