Boc anhydride mechanism
http://www.commonorganicchemistry.com/Rxn_Pages/Boc_Protection/Boc_Protection_Mech.htm WebSince late 2000s, propanephosphonic acid anhydride, sold commercially under various names such as "T3P", has become a useful reagent for amide bond formation in commercial applications. It converts the oxygen of the carboxylic acid into a leaving group, whose peptide-coupling byproducts are water-soluble and can be easily washed away.

WebBoc Anhydride Other Names: Di- tert -butyl dicarbonate Di- tert -butyl pyrocarbonate General Information: Structure: CAS Number: 24424-99-5 Molecular Weight: 218.25 g/mol Appearance: Colorless solid Melting Point: 22-24 C Boiling Point: 56-57 C Boc anhydride has a melting point of only 22-24 C. WebThe BOC (tert-butyloxycarbonyl) protecting group, chemically a di-tert-butyl dicarbonate (Boc 2 O), is probably the most common amine protecting group in non-peptide chemistry. The reaction conditions for the amine protection are quite flexible. The process usually achieves high yields and fast conversions under relatively mild conditions.

WebThe BOC group is generally one of the most sensitive to acids, so often selective deprotection in the presence of other acid sensitive groups is possible. Strong acids – organic or inorganic The use of acids or Lewis acidic reagents leads to the generation of the t-Butyl cation as an intermediate. The Boc group can be added to the amine under aqueous conditions using di-tert-butyl dicarbonate in the presence of a base such as sodium bicarbonate. Protection of the amine can also be accomplished in acetonitrile solution using 4-dimethylaminopyridine (DMAP) as the base.
