Many phytopathogenic fungi can easily infect crops, resulting in crop yield reductions. In continuation of our efforts to develop natural product (NP)‐based antifungal agents, a series of N‐phenylpyrazole sarisan hybrids 6a–v were prepared via I2‐mediated oxidative cyclization, and their structures were determined by various spectral analyses including IR, 1H‐NMR and ESI‐MS. Among all N‐phenylpyrazole...
A series of sarisan analogs containing 1,3,4‐oxadiazole moieties were synthesized by iodine‐mediated oxidative cyclization and screened in vitro for their antifungal activities at 50 μg/mL against five phytopathogenic fungi such as Valsa mali, Curvularia lunata, Alternaria alternate, Fusarium solani and Fusarium graminearum. 1,3,4‐Oxadiazole derivatives 7e, 7p, 7r, 7t and 7u exhibited potent and a...
