A convenient and efficient method for the synthesis of 2-acylbenzothiazoles from benzothiazoles and aromatic ketones using oxygen as oxidant is described. FeCl3·6H2O showed the best reactivity among the various iron salts investigated. Various functional groups were well tolerated under the optimized reaction conditions.
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.
