Formation of the imidazolinone ring under mild conditions in the presence of sodium hydride
Substituted imidazolinones containing heterocyclic carboxylic acids as substituents and possessing herbicidal properties were synthesized by cyclization of 2-amino-2,3-dimethylbutyramide with heterocyclic ethyl dicarboxylates under mild conditions. The use of NaH as base leads to a significant increase in the reaction rate and allows the preparation of the target compounds in high yields.

Soybean plants with dominant selectable trait for herbicide resistance
The utilization of a positive selection seed screening process to isolate rate variants with resistance to a herbicide is described. The ability to screen large numbers of mutagenized seed has made it feasible to pursue and isolate plants with low frequency dominant herbicide-resistance mutations. The dominant herbicide resistance mutations are useful for many applications including expanding the utility of sulfonylurea herbicides for soybean weed control, production of F1 and F2 seeds, and as selectable markers for efficient seed purification.

Nucleic acid fragment encoding herbicide resistant plant acetolactate synthase
A nucleic acid fragment encoding a herbicide-resistant plant acetolactate synthase protein is disclosed. This nucleic acid fragment contains at least one nucleotide mutation resulting in one amino acid change in one of seven substantially conserved regions of acetolactate synthase amino acid homology. This mutation results in the production of an acetolactate synthase protein which is resistant to sulfonylurea herbicide compounds compared to the wild-type protein. Transformation of herbicide sensitive plants or plant cells with the fragment results in resistance to the herbicide.
