A convenient synthetic route to 2-heteroaryl-3-hydroxybenzo[b]thiophene derivatives via K_(2)CO_(3)-promoted multicomponent cycliza-tion between o-halogenated benzaldehyde,2-methylquinolines and sulfur powder has been...
We acknowledge the National Natural Science Foundation of China(No.21472136)for financial support.
Main observation and conclusion The reaction of 2-alkynylanisoles/sulfides with SOCl_(2) and DMSO was conducted to conveniently furnish the biologically interesting 3-(methylthio)-benzo[b]furans/thiophenes via intramo...
Project supported by the National Natural Science Foundation of China (No. 20972132).
The polysubstituted thiophene derivatives were conveniently prepared by the four-component reactions of 1,3-thiazolidinedione, aromatic aldehydes, cyanoacetamide and cyclic secondary amines such as pyrrolidine, mor- p...
13C NMR chemical shifts have been calculated for structures of some substituted 3-anilino-2-nitrobenzo- [b]thiophenes (2o) and 2-anilino-3-nitrobenzo[b]thiophenes (3o) derivatives containing OH, NH2, OMe, Me, Et, ...
A facile route to 2-benzylthio-5-phenyl-3,4-disubstituted thiophenes was described. Catalyzed by sodium hydroxide, the title compounds were synthesized in moderate to good yields simply from the intramolecular aldol t...
A series of C_2-symmetrical chiral 2,5-bis(4'-alkyloxazolin-2-yl) thiophenes(thiobox) have been synthesized from thiophene-2,5-dicarboxylic acid by sequential amidation with achiral ethanolamine, conversion of hydroxy...
