The Friedel−Crafts Allylation of a Prenyl Group Stabilized by a Sulfone Moiety:  Expeditious Syntheses of Ubiquinones and Menaquinones

An efficient synthetic method for the protected p-hydroquinone compounds 4 containing the C5 trans allylic sulfone moiety has been developed by the direct Friedel−Crafts allylation of the protected dihydroquinone 2 with 4-chloro-2-methyl-1-phenylsulfonyl-2-butene (7a) or 4-hydroxy-2-methyl-1-phenyls...
