  摘要：

  Abstractmagnified imageThe one‐pot synthesis of a novel series of amino‐protected 6‐alkyl‐, 6‐aryl‐, 6‐heteroaryl‐ and 5,6‐fused‐cycloalkane 4‐trifluoromethyl‐2‐acetylaminopyrimidines, where alkyl = Me; aryl = Ph, 4‐CH3Ph, 4‐FPh, 4‐ClPh, 4‐BrPh, 4‐OCH3Ph, 4‐NO2Ph, 4,4′‐biphenyl, 1‐naphthyl; heteroaryl = 2‐thienyl, 2‐furyl and cycloalkyl = c‐C6H4, c‐C7H5 from the reaction of substituted 4‐methoxy‐1,1,1‐trifluoroalk‐3‐en‐2‐ones with 1‐acetylguanidine in acetonitrile or propan‐2‐ol as solvent, is reported. The acetylamino group of 2‐acetylaminopyrimidines was hydrolyzed under three different conditions to afford the corresponding free 2‐aminopyrimidines.

  Anilinopyrimidines are the main chemical agents for management of Botrytis cinerea. However, the drug resistance in fungi against this kind of compounds is very serious. To explore new potential fungicides against B. cinerea, a series of 4-phenyl-6-trifluoromethyl-2-amino-pyrimidine compounds (compounds III-1 to III-22) were synthesized, and their structures were confirmed by 1H-NMR, IR and MS. Most of these compounds possessed excellent fungicidal activity. The compounds III-3 and III-13 showed higher fungicidal activity than the positive control pyrimethanil on fructose gelatin agar (FGA), and compound III-3 on potato dextrose agar (PDA) indicated high activity compared to the positive control cyprodinil. In vivo greenhouse results indicated that the activity of compounds III-3, III-8, and III-11 was significantly higher than that of the fungicide pyrimethanil. Scanning electron micrography (SEM) and transmission electron micrography (TEM) were applied to illustrate the mechanism of title compounds against B. cinerea. The title compounds, especially those containing a fluorine atom at the ortho-position on the benzene ring, could maintain the antifungal activity against B. cinerea, but their mechanism of action is different from that of cyprodinil. The present study lays a good foundation for us to find more efficient reagents against B. cinerea.

  苯胺嘧啶类是防治灰葡萄孢的主要化学药剂。然而，真菌对此类化合物的耐药性非常严重。为了探索新的防治灰葡萄孢的潜在杀菌剂，合成了一系列4-苯基-6-三氟甲基-2-氨基嘧啶类化合物(III-1至III-22)，并通过1H-NMR、IR和MS确认了其结构。这些化合物大多具有优异的杀菌活性。化合物III-3和III-13在果糖明胶琼脂(FGA)上的杀菌活性高于阳性对照嘧菌胺，化合物III-3在马铃薯葡萄糖琼脂(PDA)上的活性表明其与阳性对照环丙酰菌胺相比具有高活性。温室试验结果表明，化合物III-3、III-8和III-11的活性显著高于杀菌剂嘧菌胺。通过扫描电子显微镜(SEM)和透射电子显微镜(TEM)说明了这些化合物对灰葡萄孢的作用机制。这些化合物，特别是含有苯环上邻位氟原子的化合物，能够维持对灰葡萄孢的抗真菌活性，但其作用机制与环丙酰菌胺不同。本研究为我们寻找更高效的防治灰葡萄孢的药剂奠定了良好的基础。

  Highly efficient synthesis of 6-trifluoromethylated pyrimidines based on reaction of CF3-ynones with nitrogen 1,3-binucleophiles was developed. One-pot assembly of pyrimidine core proceeds by the cascade route via aza-Michael addition - intramolecular cyclization - dehydration sequence giving the target heterocycles in excellent yields (up to 97%). When acetamidine was used as a binucleophile, the
