Di-tert-butyl dicarbonate boc2o

http://commonorganicchemistry.com/Rxn_Pages/Boc_Protection/Boc_Protection_Boc2O_Base_DMAP_Mech.htm WebDuring decarboxylation, carboxylic acids and alcohols were converted cleanly using di-tert-butyl dicarbonate (Boc2O) as a coupling reagent, which reduced by-products. In addition, the use of Boc2O resulted in the formation of tert-butyl esters. These esterifications dramatically reduced the reaction time under continuous-flow conditions, with a ...

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. Webtert-Butyl bicarbonate breaks down into CO2 (gas) and tert-butanol. Key Points: The CO2 gas that forms during the reaction should be allowed to escape. Don't run boc protections in closed systems.
