a cyanation/cyclization/acylation domino sequence enabling a rapid and efficient synthesis of diversely substituted 2-aminobenzothiazole derivatives. Notably, this reaction proceeds via an original mechanism involving an intermolecular migration of the acylgroup.

The Balz–Schiemann reaction remains a highly utilized means for preparing aryl fluorides from anilines. However, the limitations associated with handling aryl diazonium salts often hinder both the substrate scope and scalability of this reaction. To address this, a new continuous flow protocol was developed that eliminates the need to isolate the aryl diazonium salts. The new process has enabled the

The present invention provides an imide-containing benzothiazole derivative or its pharmaceutically acceptable salt, a process for the preparation thereof, and a pharmaceutical composition comprising the same. The imide-containing benzothiazole derivative or its pharmaceutically acceptable salt can selectively inhibit the protein-protein interaction between KRS and a laminin receptor (LR), thereby inhibiting migration of cancer cells. Therefore, the imide-containing benzothiazole derivative or its pharmaceutically acceptable salt may be usefully applied for preventing or treating the diseases associated with cancer cell metastasis.
access S-heterocycles and mixed N,S-heterocycles via metal-mediated dominoreactions are described. One involves a cyclocarbopalladation/cross-coupling domino process and leads to benzene-fused five- or six-membered sulfur heterocycles with a stereo defined tetrasubstituted exocyclic double bond. The other consists in a three-component dominoreaction between 2-aminophenyl disulfide, copper cyanide
