predicted to be an ideal herbicidal target. Three novel series of benzothiazole derivatives were synthesized and evaluated for their herbicidal activities against Brassica napus (rape) and Echinochloa crusgalli (barnyard grass). The preliminary bioassay indicated that most of the synthesized compounds possess promising D1 protease inhibitory activities and considerable herbicidal activities. Molecular

Development of catalytic amide bond formation reactions from readily available starting materials remains a challenging task for modern organic chemistry. Herein, we report that unactivated carboxylic esters and amines react in the presence of 10 mol % of zirconocene dichloride (Cp2ZrCl2) in toluene at 110 degrees C to afford amides in very good to excellent conversions. The Zr-catalyzed reaction is amenable for the amidation of aliphatic and aromatic carboxylic esters with primary and secondary amines. The reaction proceeds with almost complete retention of configuration for chiral esters and chiral amines. (C) 2015 Elsevier Ltd. All rights reserved.
