The 2-(p-diphenyl)-isopropyloxycarbonyl (Dpoc) residue has been chosen for the selective protection of α-amino groups in the synthesis of peptides containing additional acid-labile protecting residues. It is easily introduced into amino-acids by reacting either the mixed carbonate I or the azide III with esters or salts of amino-acids. It is split by dilute acetic acid and other weakly acidic reagents
选择2-(对-二苯基)-异丙氧基羰基(Dpoc)残基用于在合成含有其他酸不稳定保护残基的肽时选择性保护α-氨基。通过使混合的碳酸盐I或叠氮化物III与氨基酸的酯或盐反应,可以轻松地将其引入氨基酸。它被稀乙酸和其他弱酸性试剂分开,其速率允许在存在其他对酸不稳定的保护基团(尤其是衍生自叔丁醇的保护基团)的情况下进行选择性裂解
