A convenient method for removal of the t-butyl group from nucleoside bis(t-butyl) phosphates under non-acidic conditions
摘要:
A new method for selective removal of the t-butyl group from 3'-bis(t-butyl) phosphate esters 5'-O-(4,4'-dimethoxytrityl)deoxyribo-nucleosides was developed by use of Me3SiCl and Et3N. Several unexpected properties of the t-butyl group were described.
