The synthesis of the syn- 14 and anti- 13 isomers of 2(S)-phthalimidornethyl-2,3,4,4a,7,7a-hexahydro-6-oxo-5H-pyrano[2,3-b]pyrrole was accomplished starting from sodium 3,4-dihydro-2H-pyran-2-carboxylate. The isomers were separated by preparative high performance liquid chromatography. Both isomers can serve as β-bend mimetics and represent three amino acids plus the amino group of the fourth amino
所述的合成顺式- 14和抗- 13分2(异构体小号)-phthalimidornethyl甲基-2,3,4,4a,7,7A六氢-6-氧代-5- ħ吡喃并[2,3- b ]吡咯从3,4-二氢-2 H-吡喃-2-羧酸钠开始完成。通过制备型高效液相色谱分离异构体。两种异构体都可以充当β-弯曲模拟物,代表三个氨基酸加一个肽的第四个氨基酸的氨基。将内酰胺氮烷基化以提供相当于第四氨基酸残基的亮氨酸。
