WebThe t-butoxycarbamate (BOC) group is widely used to protect amines, and to a lesser extent alcohols can be protected with BOC groups. Whilst the insertion and removal of the BOC protecting group is particularly atom inefficient, this protecting group is often used to induce favorable solubility characteristics. In addition its steric bulk can ... Webindoles etc., protected with N-Boc group, can also be deprotected under basic conditions. In almost all cases the deprotection is selective only for some heterocycles under certain conditions. Specifically, the N-Boc-imidazole is deprotected with H 2 NNH 2 or NH 3 /MeOH, 3 the selective cleavage of Boc group from N-Boc imidazoles and indoles is ...
