In this paper, a high-yield, facile route for the scalable synthesis of sulfonyl 2-aroylbenzofurans via a Bi(OTf)3-mediated intermolecular double cyclocondensation of α-sulfonyl o-hydroxyacetophenones with substituted α-hydroxy arylketones under mild open-vessel reaction conditions is described. In the overall reaction, water is generated as the only byproduct. Various metal triflate-promoted reactions and conditions are investigated for the efficient one-pot (4+1) annulation reaction.

A series of novel Benzofuran-tetrazole derivatives were successfully synthesised by integrating multicomponent Ugi-azide reaction with the molecular hybridization approach. Interestingly, a number of synthesized derivatives (5c, 5d, 5i, 5l, 5q and 5s) exhibited significant reduction of aggregation of “human” amyloid beta peptide, expressing on transgenic Caenorhabditis elegans (C. elegans) strain CL4176. Further, in silico docking results have evidenced the exquisite interaction of active compounds with the help of TcAChE–E2020 complex. These findings underscore the potential of these hybrids as lead molecules against Alzheimers's disease.
Preparation of highly functionalised benzofurans from ortho-hydroxyphenones and dichloroethylene: Applications and mechanistic investigations
Schevenels, Florian,Tinant, Bernard,Declercq, Jean-Paul,Markó, István E.

Highly functionalised benzofurans have been prepared from ortho-hydroxyphenones and 1,1-dichloroethylene. The key intermediate, a chloromethylene furan, smoothly rearranged into the corresponding benzofuran carbaldehyde under acidic conditions. Some mechanistic investigations have been performed and several biologically active benzofurans have been synthesised. Copyright
