The use of a combination of amineâborane complexes and soluble palladium catalyst allows the fast deprotection of allyl carbamates under near-to-neutral conditions and without any side-formation of allylamine. Preliminary experiments indicate that palladium catalystâamineâborane systems seem ideally suited for removal of Nα-Alloc terminal groups during solid phase peptide synthesis according to the N
α-Alloc temporary protection strategy.
使用胺-硼烷复合物与可溶性钯催化剂的组合,可以在接近中性条件下快速去保护烯丙基氨基甲酸酯,且不会产生任何副产物烯丙胺。初步实验表明,钯催化剂-胺-硼烷系统似乎非常适合在固相肽合成中根据Nα-烯丙氧羰基临时保护策略去除Nα-烯丙氧羰基末端基团。
