t-Butyl Benzotriazol-1-yl Carbonate and Benzyl Benzotriazol-1-yl Carbonate. Now Reactive Amino Protective Reagents for t-Butoxycarbonylation and Benzyloxycarbonylation of Amines and Amino Acids
Sunggak Kim*, Heung Chang
New amino protective reagents, t-butyl benzotriazol-1-yl carbonate and benzyl benzotriazol-1-yl carbonate, for t-butoxycarbonylation and benzyloxycarbonylation of amines and amino acids have been developed. t-Butyl benzotriazol-1-yl carbonate reacts rapidly and cleanly with various amines and amino acids to afford N-Boc amines and N-Boc amino acids in high yields and benzyl benzotriazol-1-yl carbonate is also found to be very effective in the benzyloxycarbonylation of amino acids.
