Highly functionalised potential neuraminidase (NA) inhibitors, analogues of peramivir, were synthesised via a new and versatile method starting from a stereoselective 1,3-dipolar cycloaddition reaction between the nitrile oxide derived from 2-ethylbutanal and the commercially available and inexpensive cyclopentadiene and 1,3-cyclohexadiene, which afforded the isoxazolino-cyclopentene or cyclohexene
高功能化的潜在神经氨酸酶(NA)抑制剂(peramivir的类似物)是通过一种新的通用方法合成的,该方法从2-乙基丁醛衍生的丁腈与市售廉价的环戊二烯和1之间的立体选择性1,3-偶极环加成反应开始,3-环己二烯,分别提供异恶唑啉代-环戊烯或环己烯中间体。C = C键在不同条件下的后续反应使五个(或六个)成员碳核功能化。通过异恶唑啉环的最终打开,获得了显示氨基和羟基的其他官能化衍生物。
