General description

Thianaphthene-3-carboxaldehyde, also known as benzo[b]thiophene-3-carboxaldehyde, can be synthesized from 3-methyl-benzo[b]thiophene. It undergoes phosphine-free palladium coupling with aryl halides to form 2-arylbenzo[b]thiophenes.

Application

Thianaphthene-3-carboxaldehyde (Benzo[b]thiophene-3-carboxaldehyde) may be used as a starting material in the multi-step synthesis of anthra[2,3-b:7,6-b′]bis[1benzothiophenes (ABBTs).
It may be used in the synthesis of :
  • 6-(N,N-dimethylamino)-2-(benzo[b]thiophen-3-yl)quinazolin-4-one
  • 6-(pyrrolidin-1-yl)-2-(benzo[b]thiophen-3-yl)quinazolin-4-one
  • (Z)-2-(benzo­[b]­thio­phen-3-yl­methyl­ene)-1-aza­bi­cyclo­[2.2.2]­octan-3-one
