A novel protocol has been successfully established for the efficient synthesis of benzothiazole-tethered chromanone/coumarin scaffolds via Claisen rearrangement using a solid state melt reaction in a one-pot manner. Benzothiazole formation and Claisen rearrangement involve the cleavage of S–S and C–O bonds and formation of C–S, C═N, and C–C bonds in a single operation without using a catalyst or solvent
已经成功地建立了一种新的方案,该方案通过使用固态熔融反应以一锅方式通过克莱森重排有效合成
苯并噻唑系链的苯并二氢
吡喃酮/
香豆素支架。
苯并噻唑的形成和克莱森重排涉及在不使用催化剂或溶剂的情况下,一次操作中S–S和C–O键的裂解以及C–S,C═N和C–C键的形成。
