The synthesis of two polyhydroxylated indolizidines as potenticial glycosidase inhibitors is reported. The piperidine ring was formed by an intramolecular Mannich-type reaction between ethyl trans-4-oxo-2-butenoate and the two β-amino ketones (–)-1-(2-methyl-1,3-dioxan-2-yl)propan-2-amine and(+)-1-(benzyloxymethyl)-2-(2-methyl-1,3-dioxan-2-yl)ethylamine. The synthesis of this amine was performed in
据报道,合成了两种多羟基化吲哚里西啶作为潜在的糖苷酶抑制剂。哌啶环是由 trans-4-oxo-2-butenoate 乙酯和两个 β-氨基酮 (-)-1-(2-methyl-1,3-dioxan-2-yl) 之间的分子内曼尼希型反应形成的)丙-2-胺和(+)-1-(苄氧基甲基)-2-(2-甲基-1,3-二恶烷-2-基)乙胺。该胺的合成分八步从 L-天冬氨酸进行。框架形成的关键步骤包括二羟基化、亲核取代和还原。最后一个羟基是通过水解缩醛部分然后还原得到的酮而引入的。针对多种商业糖苷酶评估了两种合成的吲哚里西啶的抑制特性。(© Wiley-VCH Verlag GmbH & Co.
