Synthesis of m -terphenyl derivatives via domino Diels-Alder/Retro-Diels- Alder reaction of 1,3-dienic δ-sultones with alkynes

A highly regioselective synthetic method based on the domino Diels-Alder/retro-Diels-Alder reaction (DA/RDA) of 1,3-dienic δ-sultones with alkynes provides substituted m-terphenyls by elimination of SO3. A variety of δ-sultones and alkynes were examined to determine the scope of the reaction. The de novo synthesized aromatic products were obtained using thermal, microwave, and high-pressure activation.

Simple and practical one-step synthesis of new 1,3-dienic δ-sultones from terminal alkynes and some synthetic applications of these compounds

1,3-Dienic δ-sultones 4,6-diaryl-[1,2]oxathiine 2,2-dioxides were synthesized via a one-step reaction of arylalkynes with dioxane sulfotrioxide. The reactivity of various alkynes in this reaction was investigated. The resulting sultones were brominated with Br2 or N-bromosuccinimide regioselectively to sulfur and subsequently coupled with phenylacetylene using Sonogashira conditions.
