p-Quinones react smoothly with allyltrimethylsilane in the presence of 2 mol% of Bi(OTf)3 under mild reaction conditions to afford the corresponding allyl substituted benzene derivatives, p-allylquinols and allyl substituted 1,4-naphthoquinones in excellent yields with high regioselectivity. This method is very useful for the direct introduction of an allyl functionality onto a quinone moiety.

4-hydroxytetrahydropyran-2-one derivatives with general formula (I) are useful as cholesterol reducing agents as well as lipid reducing agents, serving as inhibitors of HMG-CoA reductase, and capable of inhibiting the biosynthesis of peroxidized lipids, and therefore effective for curing arteriosclerosis: STR1 wherein R1 represent hydrogen or a 2-tetrahydropyranyl group; R2 and R3 each represent hydrogen or an alkyl group having 1 to 6 carbon atoms; R4 represents hydrogen, an alkyl group having 1 to 6 carbon atoms, an alkenyl group having 2 to 6 carbon atoms, an aryl group, an aralkyl group, an acyl group, an aroyl group or a substituted sulfonyl group; A represents --CH2 CH2 --, or --CH=CH--; and n is an integer of 1 or 2, and intermediates for synthesizing the 4-hydroxytetrahydropyran-2-one derivatives are disclosed.
