合成路线1

该中间体在本合成路线中的序号：(VII)

The key intermediate, cyclopropanol (I), was prepared by titanium-mediated Kulinkovich cyclopropanation in over 80% yield as a white solid. Etherification of compound (I) with diisopropyl bromomethylphosphonate, followed by sequential desilylation, mesylation and coupling reaction with 6-chloroguanine (VII), gave compound (VIII). Finally, hydrolysis of compound (VIII) in the presence of TMSBr afforded LB-80317.
