tert-Butyloxycarbonyl protecting group - Wikipedia
The tert-butyloxycarbonyl protecting group or tert-butoxycarbonyl protecting group (BOC group) is a protecting group used in organic synthesis. 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 carbonate: Protection of the amine can also be accomplished in acetonitrile solution using 4 … WebDec 1, 2010 · PDF On Dec 1, 2010, J.C.
