Reaction of Carboxonium Ions of Cyclic Acetals, IX. - Synthesis of Rosefuran and Structurally Related Terpene-like Esters, Alcohols, and Olefins
Thermolysis of the 4-(o-toluoyloxy)-1,3-dioxolanes 4 leads to the furans 6/7 which, via Grignard reaction, can be converted into the alcohols 8/9.Subsequent dehydratization affords the olefins 10/11, e.g. rosefuran (10a).
