—— | (E)-6-(4-hydroxy-4-phenylbut-1-enyl)-2,2-dimethyl-4H-1,3-dioxin-4-one | 1416168-45-0 | C16H18O4 | 274.317 |
We herein report biomimetic syntheses of 6-substituted salicylates from the cross metathesis of 2,2-dimethyl-6-vinyl-1,3-dioxin-4-one with homoallylic alcohols, oxidation, and aromatization of the intermediate enone–dioxinones. Of particular note is the use of the catalyst 1,4-diazabicyclo[2.2.2]octane in the microwave thermolytic ketene generation and trapping, cyclization, and dehydration reaction sequence.
