title: Expedient approach to chiral cyclobutanones: asymmetric synthesis of cyclobut-G.
abstract: 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.
