Expedient Approach to Chiral Cyclobutanones: Asymmetric Synthesis of Cyclobut-G
摘要:
An efficient one-pot asymmetric synthesis of cyclobutanones from chiral enol ethers is described. The approach is illustrated with alkyl- and functionalized alkyl-substituted enol ethers (nine examples). A new enantioselective synthesis of cyclobut-G (Lobucavir) could thus be achieved.
