Organic compounds -- part of the class 532-570 series November recently filed with US Patent Office 11/09

20090292115 - 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...
