The first short synthesis of the dipeptide mimetic (3S, 6S, 9S)-6-amino-5-oxoindolizidine-3-carboxylic acid 1 and its Z-protected derivative 9 is described, employing the Schoellkopf bislactim-ether methodology, followed by a highly specific intramolecular reductive amination and spontaneous lactamization. These 6,5-fused bicyclic lactams may be viewed as conformationally restricted alanyl-proline
使用Schoellkopf双内酯醚方法,对二肽模拟物(3 S,6 S,9 S)-6-氨基-5-氧代吲哚并咪唑-3-羧酸1及其Z保护的衍生物9的首次简短合成进行了描述,然后进行高度特异性的分子内还原胺化和自发内酰胺化。这些6,5-稠合的双环内酰胺可被视为构象受限的丙氨酰基-脯氨酸β-转角模拟物。
