Mutasynthesis Generates Antibacterial Benzothiophenic-Containing Nosiheptide Analogues

Journal of Natural Products, 2022
Nosiheptide is a bicyclic thiopeptide featuring an indole-containing side ring, which is biologically important in maintaining its potent antibacterial activity. By using mutational biosynthesis, the pharmaceutically significant benzothiophene was introduced into the nosiheptide biosynthetic pathway, resulting in the generation of three bioactive ...

Visible Light Photocatalytic Synthesis of Benzothiophenes

Organic Letters, 2012
The photocatalytic reaction of o-methylthio-arenediazonium salts with alkynes yields substituted benzothiophenes regioselectively through a radical annulation process. Green light irradiation of eosin Y initiates the photoredox catalysis. The scope of the reaction was investigated by using various substituted diazonium salts and different alkynes.

Pummerer chemistry of benzothiophene S-oxides: Metal-free alkylation and arylation of benzothiophenes

Phosphorus, Sulfur, and Silicon and the Related Elements, 2019
Functionalized benzothiophenes are important constructs found in molecules with wide ranging biological activity and in organic materials. An efficient, metal-free approach to C3 and C2 arylated and alkylated benzothiophenes is summarized in this review. The strategy utilizes synthetically unexplored yet readily accessible benzothiophene S-oxides in an

Plasma polymerization of 1-benzothiophene

Journal of Applied Physics, 1991
Semiconductive thin organic polymer films have been prepared by the plasma polymerization of 1-benzothiophene. Characteristics of the polymeric products such as their electrical conductivities, optical properties, and electron spin properties have been examined in detail.

Benzofuran-/Benzothiophene-Incorporated NIR-Absorbing Triphyrins(2.1.1)

Organic Letters, 2018
Novel benzofuran-/benzothiophene-incorporated triphyrins(2.1.1) were synthesized using readily available precursors under mild reaction conditions. The X-ray structure revealed that the benzofuran-incorporated triphyrin(2.1.1) macrocycle was slightly ruffled.

Thieno[2,3-b][1] benzothiophen and thieno[3,2-b][1]benzothiophen. Part I. Preparation

Journal of the Chemical Society C: Organic, 1970
Benzo [b]thiophen-2-thiol and its 5- and 7-chloro-derivatives were prepared by treatment of the approriate 2-benzo[b]thienyl-lithium derivative with sulphur. Benzo [b]thiophen and its 5-bromo- and 7-chloro-derivatives were sulphonated in the 3-position.

DFT Research on Benzothiophene Pyrolysis Reaction Mechanism

The Journal of Physical Chemistry A, 2019
Thiophene sulfur is the most stable organic sulfur species in petroleum coke, among which benzothiophene accounts for a significant portion. Removal of benzothiophene will help to gain ultralow desulfurization. In this work, a density function theory (DFT) method was adopted to investigate benzothiophene pyrolysis mechanism.

Indole- and benzothiophene-based histamine H3 antagonists

Bioorganic & Medicinal Chemistry Letters, 2010
Previous research on histamine H(3) antagonists has led to the development of a pharmacophore model consisting of a central phenyl core flanked by two alkylamine groups. Recent investigation of the replacement of the central phenyl core with heteroaromatic fragments resulted in the preparation of novel 3,5-, 3,6- and 3,7-substituted indole and 3,5 ...
