An exclusive thiophene-fused polycyclic I-conjugated 2-arylbenzo[4,5]thieno[2,3-d]thiazole skeleton was constructed via a one-pot CuCl-mediated three-component reaction, using 2-(2-bromophenyl)acetonitrile and aromatic aldehydes as substrates and elementa

A novel and direct synthesis of various 2-aminobenzo[b]thiophenes has been developed. The reactions were catalyzed by a combination of Pd(dppf)Cl2 and dppf using odorless and cheap Na2S2O3 as the sulfur source. This strategy allowed us to synthesize important 2-aminobenzo[b]thiophene scaffold more efficiently and conveniently.

(Chemical Equation Presented). A tolerant reaction: Functionalized tertiary amines have been prepared by the oxidative coupling of amidocuprates with chloranil used as the oxidant (see Scheme). A high tolerance of functional groups and insensitivity to steric hindrance characterize this general amination reaction.

In the reaction of higher order cyanocuprates with N,O-bis(trimethylsilyl)hydroxylamine delivery of the NHSiMe3 moiety to one of the anionic ligands in the cuprate takes place even in the absence of external bases according to an "electrophilic amination" protocol.Details of the methodology are given, and the reaction mechanism is analyzed in terms of interception by a mixed bis-metal cluster of a lithium N-silyl-N-siloxyamide, followed by intramolecular C-N coupling.This method is applicable to cyanocuprates bearing aromatic, heteroaromatic, and saturated aliphatic ligands.A number of 2-amino-substituted heterocycles, not easily accesible by normal routes, can be obtained with the aid of a stabilizing silylation at the nitrogen atom.
THERMAL REACTIVITY OF 2-AZIDO- AND 3-AZIDO-BENZOTHIOPHENE WITH DIALKYLAMINES AND ALKANETHIOLS

On thermolysis in diethyl- or dimethyl-amine both 3-azido- and 2-azidobenzothiophene afford the appopriate 3-(dialkylamino)-2-aminobenzothiophene in good yield, whereas in ethyl or butyl mercaptan at room temperature, these azides smoothly lead to 2-(alkylthio)-3-amino- and 3-(alkylthio)-2-amino-benzothiophene, respectively.
