(including two natural products), 5-amino-3,4-dihydroxypiperidines, 3,4,5-trihydroxypipecolic acids, and 2-(aminomethyl)-3,4,5-trihydroxypiperidines is reported. The procedure used a double reductive amination or a Strecker reaction, starting from differently protected aldehydes readily synthesized on a gram scale from D-mannose. The biological activities of the target compounds were evaluated, and some of
合成不同取代的 3,4,5-三羟基哌啶(包括两种天然产物)、5-氨基-3,4-二羟基哌啶、3,4,5-三羟基哌啶酸和 2-(氨基甲基)-3 的一般策略,4,5-三羟基哌啶被报道。该程序使用双还原胺化或 Strecker 反应,从不同保护的醛开始,这些醛很容易从 D-甘露糖以克级规模合成。对目标化合物的生物活性进行了评价,其中一些化合物对α-L-岩藻糖苷酶和β-葡萄糖苷酶有中度抑制作用。
