报道了使用氯烯烃二肽等排物(CADI)的拟肽收敛合成的改进方法。在该合成中,可以通过Evans syn aldol反应,由与每种氨基酸原料相对应的N和C末端类似物,生产Fmoc-或Boc保护的羧酸,然后利用Ichikawa烯丙基氰酸酯重排进行[3.3]σ重排。反应。通过这种策略,可以将Fmoc保护的CADI直接用于固相肽合成。使用这种方法,我们还确定了含CADI的环[-Lys-Leu-Val-Phe-Phe-]拟肽,它是比母体肽更好的淀粉样β聚集抑制剂。
The reduction of the C=Cdouble bond of some unsaturated alpha-chloro esters was investigated by means of cloned and overexpressed enoate reductases. The results were compared with those obtained by employing baker's yeast whole cells. The anti stereochemistry of hydrogen additions was confirmed by deuterium labeling experiments.
