Synthetic method for N-alkyl(benzo)thiazole

The invention provides a synthetic method for N-alkyl(benzo)thiazole. The synthetic method comprises the following steps: putting 0.4-0.8 mmol of a carbonyl compound, 0.4-0.8 mmol of p-toluenesulfonylhydrazide and 4-10 mL of a solvent in a flask and carrying out a reaction at 30 DEG C to 80 DEG C for 1 to 3 h; adding 0.4 mmol of 2-aminothiazole, 0.4-0.8 mmol of metal copper salt and 0.4-1.2 mmolof an alkali substance into the above reaction system, carrying out heating to 100 DEG C to 150 DEG C, and continuing the reaction for 2 h to 5 h; terminating the reaction to obtain a reaction productA; and subjecting the product A to purification and impurity separation so as to obtain pure N-alkyl(benzo)thiazole. According to the invention, the intermediate sulfonyl hydrazone is prepared from the carbonyl compound and sulfonyl hydrazide, and reacts with a 2-aminothiazole substance in the presence of a catalyst and under alkali conditions to obtain N-alkyl(benzo)thiazole. The synthetic method of the invention has the advantages of simple operation, low cost, high product yield and wide application range of a substrate. At the same time, the established method can also realize the synthesis of the anti-inflammatory drug fanetizole, and thus has high practical value.

Pd-PEPPSI-IPentAn Promoted Deactivated Amination of Aryl Chlorides with Amines under Aerobic Conditions

We report herein a highly efficient Pd-catalyzed amination by "bulky-yet-flexible" Pd-PEPPSI-IPentAn complexes. The relationship between the N-heterocyclic carbenes (NHCs) structure and catalytic properties was discussed. Sterically hindered (hetero)aryl chlorides and a variety of aliphatic and aromatic amines can be applied in this cross-coupling, which smoothly proceeded to provide desired products. The operationally simple protocol highlights the rapid access to CAr-N bond formation under mild conditions without the exclusion of air and moisture.
