Design,synthesis, and bioactivity evaluation of novel thiochromanone derivatives containing an oxime or oxime ether moiety

In this study, using botanical active component thiochromanone as the lead compound, a series of novel thiochromanone derivatives containing an oxime or oxime ether moiety were designed and synthesized. The half-maximal effective concentration (EC₅₀) values of compound 4a against Xanthomonas oryzae pv. oryzae (Xoo), Xanthomonas oryzae pv. oryzicolaby (Xoc), and Xanthomonas axonopodis pv. citri (Xac) were 6, 10, and 15 μg/ml, respectively, which were superior to those of Bismerthiazol and Thiodiazole-copper. Meanwhile, compound 4a also revealed better antifungal activity against Botrytis cinerea, with the EC₅₀ value of 18 μg/ml, than that of Carbendazim. To the best of our knowledge, this is the first report on the antibacterial and antifungal activities of this series of novel thiochromanone derivatives containing an oxime or oxime ether moiety.

Unusually Facile Pyrrolization of 2-Acetylcoumarone Oxime with Acetylene

The oxime of 2-acetylcoumarone reacts with acetylene under pressure in the system KOH-DMSO unusually readily forming 2-(2-pyrrolyl)coumarone and the corresponding O-vinyl oxime. Under more rigid conditions 2-(1-vinyl-2-pyrrolyl)coumarone is formed. The possibility of a two-stage transformation of 2-acylcoumarones into 2-pyrrolylcoumarones has therefore been demonstrated for the first time.__________Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 4, pp. 524–529, April, 2005.
