Synthesis of Dibenzothiophene and 1,4-Dihydrodibenzothiophene Derivatives via Allylic Phosphonium Salt Initiated Domino Reactions

Two efficient synthetic protocols were developed for the synthesis of dibenzothiophene and 1,4-dihydrodibenzothiophene using thioaurones and allylic phosphonium salt. Mild reaction conditions, a one-pot procedure, and easily accessible starting materials make these protocols powerful tools for the synthesis of these compounds, which are often used in material and pharmaceutical sciences.

The synthesis of methyl (2E,4Z)-2,4-decadienoate was based on a C 4 + C6 scheme. The coupling reaction took place between the 1-hexanale and phosphonium salt of methyl 1-bromocrotonate in a Wittig condensation. Methyl (2E,4Z)-2,4-decadienoate is a minor component of the sex pheromone of the bark beetle Pityogenes chalcographus.
