Synthesis method of benzothiazolone compound

The invention discloses an economical and mild. The method adopts o-iodoaniline, elemental sulfur and DMF as raw materials, so that the yield of a target product of up to 3 hours can be obtained only 90%, and the synthesis strategy is compatible with a wide range of functional groups.

Method for synthesizing benzothiazolone-based and 1,3-disubstituted urea-based derivatives through activation of CO2

The present invention relates to a method for synthesizing benzothiazolone-based and 1,3-disubstituted urea-based derivatives through activation of CO2. According to the present invention, an inexpensive and easily-available sulfur-containing metal salt compound is first used as an activation catalyst for CO2, and a reaction raw material and CO2 are converted into a corresponding target compound at a low reaction temperature under a low CO2 pressure; and the method has high atomic economy, can reduce the generation of by-products, meets the standards of environmental friendliness and environmentally friendly chemistry, and is the effective way capable of completely utilizing CO2 as the renewable resource, developing new energy and achieving the beneficial cycle of carbon in nature.

CuI-catalyzed one-pot synthesis of benzothiazolones from 2-iodoanilines-derived carbamates and sodium sulfide

A copper-catalyzed procedure was developed for assembling benzothiazolones from ethyl 2-iodophenylcarbamates and sodium sulfide. A number of functional groups, such as methoxy, acyl, amide, carboxylate, trifluoromethyl, fluoro, and chloro, were tolerated under these conditions, providing benzothiazolones in good yields.
