Abstract:

: Benzo[b]thiophenes are aromatic heterocyclic compounds containing benzene and thiophene rings. This class of heterocycles is present in a large number of natural and non-natural compounds. Benzo[b]thiophene derivatives have a broad range of applications in medicinal chemistry such as antimicrobial, anticancer, antioxidant, anti-HIV and antiinflammatory activities. The use of benzo[b]thiophene derivatives in other fields has also been reported. Various benzo[b]thiophenes compounds have been employed as organic photoelectric materials, while several benzo[b]thiophenes have been used as organic

Abstract:

Hydrodesulphurization of benzo[b]thiophene and 2,3-dihydrobenzo[b]thiophene on Mo/alumina and Co-Mo/alumina catalysts has been studied in a flow reactor at atmospheric pressure and temperature 543 K. The amount of dihydrobenzo[b]thiophene formed in hydrodesulphurization of benzo[b]thiophene and the amount of benzo[b]thiophene formed in hydrodesulphurization of dihydrobenzo[b]thiophene were much lower on Co-Mo catalyst then on Mo catalyst. The equilibrium constant of the hydrogenation of benzo[b]thiophene to dihydrobenzo[b]thiophene at 543 K was determined. This partial equilibrium was attained

Abstract:

A non classical rearrangement is observed when thiopheno[c] and [b]bishomotropones react with ethanedithiol, leading to a naphtho[1,8-bc]thiophene and (or) a benzo[b]thiophene. The structure of the products is supported by deuterium labelling, 1H nmr spectra, and X-ray analysis of 5,6-diphenyl naphtho[1,8-bc]thiophene. A mechanism is proposed which implies an electronic transfer between a "soft" nucleophile and a "hard" acid, in the key step.

AbstractA series of 12H-[1]benzo[4′′,5′′]thieno[2′′,3′′:4′,5′]thieno[2′,3′:4,5]thieno[3,2-b]indoles were efficiently prepared in three steps starting from available benzo[b]thieno[2,3-d]thiophen-3(2H)-ones. These fused ketones were treated with the Vilsmeier reagent and hydroxylamine hydrochloride to give the corresponding 3-chlorobenzo[b]thieno[2,3-d]thiophene-2-carbonitriles, which then reacted with methyl sulfanylacetate to form methyl 3-aminobenzo[4′,5′]thieno[2′,3′:4,5]thieno[3,2-b]thiophene-2-carboxylates, in accordance with the Fiesselmann thiophene synthesis protocol.

Abstract:

Fiesselmann thiophene synthesis was applied for the convenient construction of thieno[3,2-b]thiophene derivatives. Thus, new 5- or 6-aryl-3-hydroxythieno[3,2-b]thiophene-2-carboxylates were obtained by condensation of 5- or 4-aryl-3-chlorothiophene-2-carboxylates, respectively, with methyl thioglycolate in the presence of potassium tert-butoxide. The saponification of the resulting esters, with decarboxylation of the intermediating acids, gave the corresponding thieno[3,2-b]thiophen-3(2H)-ones. The latter ketones were used to synthesize new N,S-heterotetracenes, namely 9H-thieno[2',3':4,5]thie

Abstract:

Methods for the synthesis of keto derivatives of the little studied naphtho[1,8-bc]thiophene system have been developed. Using the readily available benzothiophene derivative 6,7-dihydrobenzo[b]thiophen-4(5H)-one 4, a 3-keto-naphtho[1,8-bc]thiophene 14 was synthesized by a tin(IV) chloride catalyzed cyclization of the acid chloride derivative of the saturated acid 13b. The bicyclic ketone 4 was also used to prepare the keto-sulfoxide 7, which was cyclized to the 4-keto-naphtho[1,8-bc]thiophene system 9 in a Pummerer-type rearrangement.
