A new synthetic strategy has been devised to access a variety of polyhydroxylated piperidines belonging to the azasugar class of glycosidase inhibitors. The key precursor (3aR, 7aR)-5-benzyl-2,2-dimethyl-7-methylenehexahydro[1,3]dioxo[4,5-c]pyridine is obtained by photoinduced electron transfer (PET) cyclization of the corresponding α-trimethylsilylmethylamine radical cation to the tethered acetylene functionality. The new molecules have been evaluated for inhibitory properties for certain β-glycosidases and have been found to be moderate to weak inhibitors of the enzymes under study.
一种新的合成策略被设计用于获得属于糖氨基酸酶抑制剂类的多羟基化哌啶的多样性。关键前驱体 (3aR, 7aR)-5-苄基-2,2-二甲基-7-亚烯基六氢[1,3]二氧杂[4,5-c]吡啶是通过光诱导电子转移(PET)环化反应获得的,该反应涉及相应的α-三甲基硅基甲基氨基自由基阳离子与连接的炔烃功能团。新分子的抑制特性已被评估,结果发现它们对某些β-糖苷酶的抑制作用为中等到弱。
