Several boron-containing small molecules have been approved by the US FDA to treat human diseases. We explored potential applications of boron-containing compounds in modern agriculture by pursuing multiple research and development programs. Here, we report a novel series of multi-substitution benzoxaboroles (1–36), a compound class that we recently reported as targeting geranylgeranyl transferase I (GGTase I) and thereby inhibiting protein prenylation (Kim et al., 2020). These compounds were designed, synthesized, and tested against the agriculturally important fungal pathogens Mycosphaerella fijiensis and Colletotrichum sublineolum in a structure–activity relationship (SAR) study. Compounds 13, 28, 30, 34 and 36 were identified as active leads with excellent antifungal MIC95 values in the range of 1.56–3.13 ppm against M. fijiensis and 0.78–3.13 ppm against C. sublineolum.
BORON CONTAINING COMPOUNDS AND THEIR USES
-
Paragraph 0224-0225, (2020/03/29)
The present disclosure contemplates novel boron-containing compounds and their uses as active agents that exhibit pesticidal activity such as antimicrobial, insecticidal, arachnicidal, and/or anti parasitic activity. An agrochemical composition containing such a compound and its use in, animal health, agriculture, or horticulture is also contemplated. A method for promoting plant performance and/or controlling, reducing, preventing, ameliorating, or inhibiting microbes, insects, arachnids, and/or parasites on or in an animal, a plant, a plant part, plant propagation material, and/or harvested fruits or vegetables is also contemplated.

Organoboron compounds are valuable molecules of increasing interest in organic synthesis, catalysis, biology and medicine. Among them, benzoxaboroles emerged as promising building blocks for numerous research programs. In this letter, we communicate the development of new conditions for the one-pot benzoxaborole synthesis by SiliaCat DPP?Pd catalysis using diboronic acid as the boron source. This low cost and sustainable strategy permitted the preparation of a useful range of benzoxaborole building blocks. Finally, the transformation was extended to a continuous flow process using our Vapourtec system. (Figure presented.).
