N-methylene tertiary butyl amine
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.
