We report the first example of B(CF)-catalyzed O-H insertion reaction of sulfoxonium ylides and carboxylic acids, achieving efficient construction of diester moieties under metal-free condition. This protocol is characterized by broad substrate tolerance, particularly for various phenylacetic acids, and good compatibility with water/air condition, which is superior to most other methods.
View Article and Find Full Text PDFA novel Rh-catalyzed cascade reaction of pyridotriazoles with iodonium ylides is reported. This one-pot procedure involves a triazole-directed -position C-H carbene insertion, followed by intramolecular denitrogenation annulation. It was noteworthy that this reaction provided straightforward access to 1-isochromene frameworks with excellent yields (up to 94% yield).

However, the biocontrol strains used for the control of are insufficient. In the present study, antagonistic strain B1302 from the rhizosphere of wheat were isolated and identified as based on their morphological, physiological, and biochemical characteristics, and their 16S rDNA sequence.
