been synthesized from the N- to the C-terminus by the ‘azirine/oxazolone method’ under solid-phase conditions. In this convenient method for the synthesis of sterically demanding peptides on solid-phase, 2H-azirin-3-amines are used to introduce the α,α-disubstituted α-amino acids without the need for additional reagents. Furthermore, the synthesis of poly(Aib) sequences has been explored.
包含各种α,α-二取代的α-氨基酸的肽,例如α-氨基异丁酸(Aib),1-氨基环戊烷-1-羧酸,α-甲基苯丙氨酸和3-氨基-3,4,5,6-四氢在固相条件下,通过“叠氮基/恶唑酮法”从N-至C-末端合成了-2 H-吡喃-3-羧酸。在这种方便的在固相上合成空间上需要的肽的方法中,使用2 H-叠氮基-3-胺来引入α,α-二取代的α-氨基酸,而无需额外的试剂。此外,已经研究了poly(Aib)序列的合成。
