Thus, the scope of a novel synthetic method was extended to synthesis of amides from N -Boc-protected amines ( Table 4 ).
WebApplication Note – N-Boc protection Introduction N-Boc protection involves the reaction between an amine and boc anhydride. It allows to generate N-tert-butylcarbamates, which are stable toward a variety of routinely used conditions. N-Boc protection is one of the most widely used reaction in medicinal chemistry. WebIn addition its steric bulk can be employed to direct chemistry to desired sites, or block reaction in close proximity. Also, removal of BOC under mild conditions makes it useful …
