Using N-acetyl-D-glucosamine as a starting material, the anti-influenza drugs oseltamivir and tamiphosphor were synthesized via a pivotal intermediate of aldehyde 8. An intramolecular Horner–Wadsworth–Emmons reaction was utilized to construct the highly functionalized cyclohexene ring. The existing N-acetyl group was transformed into an azido group for the subsequent aziridination, followed by implantation of a 3-pentoxy group of the desired stereochemistry.
以N-乙酰-D-葡萄糖胺为起始材料,通过醛中间体8合成抗流感药物奥司他韦和塔米福韦。使用了一个分子内Horner-Wadsworth-Emmons反应来构建高度官能化的环己烯环。现有的N-乙酰基被转化为叠氮基,以进行后续的氮杂环化反应,随后植入所需立体化学的3-戊氧基团。
