To discover an efficient and convenient method to synthesize C2-arylacylated benzothiazoles as potential drug scaffolds, a novel [bis(trifluoroacetoxy)iodo]benzene(PIFA)/KOH synergistically promoted direct ring-opening C2-arylacylation reaction of 2H-benzothiazoles with aryl methyl ketones has been developed. Various substrates were tolerated under optimized conditions affording the C2-arylacylation
A Novel Self-Sequence Reaction Network Involving a Set of Six Reactions in One Pot: The Synthesis of Substituted Benzothiazoles from Aromatic Ketones and Anilines
and readily available aromaticketones and anilines as starting materials resulted in the construction of 2-acylbenzothiazoles via a novel self-sequence reaction network, which assembles six reactions in onepot. The reaction network not only supplied a novel method for constructing complex molecules but also provided a typical example for logical self-organization synthesis.
