Abstract:
Background: Benzo[b]furan derivatives are oxygen-containing heterocyclic compounds consisting of fused benzene and furan rings and are present in a large number of natural and non-natural compounds. This class of compounds has a wide spectrum of biological activities, such as antiarrhythmic, anticancer, inflammatory, antioxidant, antimicrobial, and antiviral. Furthermore, benzo[b]furan derivatives have also been applied in various areas, such as organic electroluminescence device materials and organic dyes, photosensitizing material, organic synthesis as building blocks or intermediates. : Bec

Abstract:
An efficient copper-promoted hydration reaction and its application in the synthesis of benzo[b]furan and benzo[b]thiophene derivatives is presented starting from readily available 2-fluorophenylacetylene derivatives. The key annulation step involves the hydration of the C–F bond of 2-fluorophenylacetylene derivatives followed by an intramolecular annulation to afford benzo[b]furan and benzo[b]thiophene derivatives. Moreover, structurally important 2,2'-bisbenzofuran scaffolds are provided in good yields.

Abstract:
Thieno[3,2-b]benzofuran was synthesized starting from benzo[b]furan-3(2H)-one or benzo[b]furan-2-carbaldehyde. Electrophilic substitution reactions such as bromination, formylation, acetylation or nitration, take place in position 2. An electron donating group in position 2 directs further electrophilic substitution into positions 3 and 6, whereas compounds with an electron acceptor in position 2 are substituted exclusively in position 6. Metallation with butyllithium took place in position 2. The 1H and 13C NMR signals of the title compound were fully assigned.

A palladium-free and ligand-free reaction condition for Sonogashira- type coupling has been developed, this catalytic system is cheap and easily removed, and provide a good yield. Total synthesis of antimicrobial molecule was accomplished in six steps. This novel route was starting from the 4-methylanisole 64. The iodination of compound 64 by treating with NIS in the presence of TMSCl can provide the 90% yield. After the copper(II) chloride
