WebCarboxyl Hydroxyl ( 1,2-; 1,3-Diols) What are protective groups? A protective group (also referred to as "protecting group") is a reversably formed derivative of an existing functional group in a molecule. 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.
