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.

SYNTHETIC OLIGOGLUCOSAMINES FOR IMPROVEMENT OF PLANT GROWTH AND YIELD

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.

Studies directed to the synthesis of oligochitosans - Preparation of building blocks and their evaluation in glycosylation studies

Thioglucosaminides with four different N-protecting groups, Troc, Phth, Alloc and PNZ could selectively be benzoylated at the C3 and C6-hydroxy groups in good yields without the requirement for low-temperature techniques. These reactions could be performe

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.

Programmable one-pot oligosaccharide synthesis

In an effort to develop a broadly applicable approach to the facile one- pot synthesis of oligosaccharides, the reactivity of a number of p- methylphenyl thioglycoside (STol) donors which are either fully protected or have one hydroxyl group exposed has b
