Abstract
The benzo[b]thiophene nucleus is ubiquitous in biologically and pharmaceutically
important compounds. These moieties are highly important in materials science. The synthesis
of benzothiophene as a privileged structure has readily become a subject of great interest
and actively pursued in recent years. This review focuses on facile and convenient methods of
synthesis of benzo[b]thiophene based molecules through different transition metals catalyzed
reactions.

Abstract
A highly torquoselective thermal triene 6π electrocyclization controls the relative stereochemistry between the C3 and C18 stereocenters of the dodecahydroindolo[2,3-a]benzo[g]quinolizine skeleton of reserpine-type alkaloids. Employing a tandem cross-coupling/electrocyclization protocol allowed us to form the requisite triene and ensure its subsequent cyclization. A novel low-temperature dibromoketene acetal Claisen rearrangement established the requisite exocyclic dienylbromide precursor for the palladium-catalyzed cross-coupling reaction.

Abstract
Described is the synthesis of novel arylated and alkynylated 2,4′‐diphenyl sulfones based on what are, to the best of our knowledge, the first palladium(0)‐catalyzed cross‐coupling reactions of bis(triflates) of 2,4′‐bis(hydroxy)diphenyl sulfone. The reactions proceed with very good site‐selectivity.
