Under cobalt catalysis, diethylzinc mediates the conjugate reduction of αβ-unsaturated amides to produce ethylzinc enolates that react with ketones in situ to produce tertiary alcohol-containing aldol products with up to >19:1 diastereoselectivity.

To find new antibacterial agents, 25 novel amide derivatives containing an 1,3,4-oxadiazole moiety were designed and synthesized, and their antibacterial activity against Xanthomonas oryzae pv. oryzicola (Xoc) and Xanthomonas oryzae pv. oryzae (Xoo) were tested. Interestingly, all target compounds showed excellent antibacterial activities against Xoc and Xoo. The EC50 values of compounds 1–25 against Xoc and Xoo were 1.2–4.0?mg/L and 0.5–2.3?mg/L, respectively, which were significantly superior to those of the thiodiazole copper (95.1 and 89.0?mg/L) and bismerthhibol (73.8 and 68.8?mg/L). For example, the EC50 values of compound 16 against Xoc and Xoo were 1.7 and 0.5?mg/L, respectively. Meanwhile, the curative and protection activity of compound 16 against rice bacterial leaf blight were 42.4% and 42.1%, respectively, which were superior to the control of jiahuangxianjunzuo (34.1% and 32.6%) and thiodiazole copper (33.0% and 27.1%). In addition, compound 16 might suppress the cell growth of Xoo by inhibiting the production of extracellular polysaccharide, the formation of biofilm, changes the cell membrane permeability, and cell surface morphology.

An enantioselective three-component reaction was developed for the synthesis of tetrahydropyridazinones employing chiral α,β-unsaturated acylammonium salts, malonates, and azodicarboxylates. An initial α-amination of a malonate with an azodicarboxylate an
