The reaction of D-(–)-pantolactone with ammonia leads to the formation of D-pantoamide, which reacts with Ас2О and HClO4 to give 5-[2-(acetoxy)-1,1-dimethylethyl]-2-methyl-4-oxo-4,5-dihydro-1,3-oxazolium perchlorate. The obtained 2-methyl-1,3-oxazolium perchlorate readily reacts with aromatic aldehydes to afford 2-(2-arylvinyl)-1,3-oxazolium perchlorates. The plant protecting properties of the obtained compounds were studied. We found that 2-(2-arylvinyl)-4-oxo-4,5-dihydro-1,3-oxazolium perchlorates are effective as antidotes towards herbicide 2,4-D but have no plant growth activity.
