SYNTHETIC OLIGOGLUCOSAMINES FOR IMPROVEMENT OF PLANT GROWTH AND YIELD

The disclosure provides formulations comprising synthetic oligoglucosamines and methods for improving plant growth and crop yield therewith. These formulations may be applied to propagating materials, including seeds and other regenerable plant parts, including cuttings, bulbs, rhizomes and tubers. They may also be applied to foliage, or soil either prior to or following planting of propagating materials. Such applications may be made alone or in combination with fungicides, insecticides, nematicides and other agricultural agents used to improve plant growth and crop yield.

SYNTHETIC SALT COMPLEXES FOR IMPROVEMENT OF PLANT GROWTH AND YIELD

The disclosure provides agricultural compositions comprising oligoglucosamine salt complexes and methods for improving plant growth and crop yield. These compositions may be applied to plant propagating materials, including seeds and other regenerable plant parts, including cuttings, bulbs, rhizomes and tubers. They may also be applied to foliage, or soil either prior to or following planting of plant propagating materials. Such applications may be made alone or in combination with fungicides, insecticides, nematicides and other agricultural agents used to improve plant growth and crop yield.

COMBINATORIAL LIBRARIES

Synthetic mixtures comprising two or more synthetic oligoglucosamine based derivatives have been found to be useful in agricultural compositions for promoting seed germination. The disclosed synthetic mixtures may be applied to plant propagating materials, including seeds and other regenerable plant parts, including cuttings, bulbs, rhizomes and tubers. They may also be applied to foliage, or soil either prior to or following planting of plant propagating materials. Such applications may be made alone or in combination with fungicides, insecticides, nematicides and other agricultural agents used to improve plant growth and crop yield.

Regioselective control in the oxidative cleavage of 4,6-o-benzylidene acetals of glycopyranosides by dimethyldioxirane

"Chemical Equation Presentation" The oxidative cleavage of 4,6-O-benzylidene acetals of glycopyranosides using dimethyldioxirane (DMDO) leads to the corresponding hydroxy-benzoates in excellent yields. With a proper choice of the neighboring protecting groups, this oxidative fragmentation provides the 6- or 4-hydroxyl derivatives in a highly regioselective manner.

PROCESSES FOR CHEMICAL SYNTHESIS OF LIPOCHITOOLIGOSACCHARIDES

Processes for the synthesis of lipochitooligosaccharides were developed. A fully acylated oligoglucosamine precursor is prepared and reacted with a glucosamine monomer that has an amine protecting phthaloyl group. With removal of the phthaloyl group, a fatty acid may be added on the terminal glucosamine unit, forming a lipochitooligosaccharide. The processes can be adapted for use on a commercial scale.

Low molecular weight polyglucosamines and polygalactosamines

Compositions containing enriched populations of beta linked low molecular weight polymers of galactosamine and glucosamine are provided. The compositions are useful, for example, as antibacterial additives for food and other edible applications, as precursors for synthesizing other biologically active molecules related to chitin/chitosan oligomers, and/or as pharmaceutical compounds.
