Efficient and novel one-pot synthesis of polycycles bearing cyclols by FeCl3-promoted [2 + 2] cycloaddition: application to cannabicyclol, cannabicyclovarin, and ranhuadujuanine A
摘要:
利用 FeCl3 促进的 [2 + 2] 环加成反应,从容易获得的具有多种取代基的苯并吡喃中开发出简单易行的合成路线,用于制备具有生物学意义的环醇多环。作为该方法的例子,大麻二环醇、大麻二环素和ranhuadujuanine A 的一步合成以良好的产率完成。
Concise Total Synthesis of Biologically Interesting Mallotophilippens C and E
摘要:
This paper describes a new and efficient synthetic approach for biologically interesting natural mallotophilippens C and E. The key strategies involved ethylenediamine diacetate-catalyzed benzopyran fort-nation reactions and base-catalyzed aldol reactions.
