Processes and materials for the synthesis of sugar esters found in natural tobacco
A process and materials method for making a glucose tetraester may include reacting glucose with a carboxylic acid to create a glucose pentaester. The glucose pentaester was reacted with a basic reagent to create a glucose tetraester. Glucose was reacted with a carboxylic acid anhydride in the presence of 4-dimethylaminopyridine to create a glucose pentaester product. The glucose pentaester reaction product was separated. The glucose pentaester reaction product was reacted with a basic reagent, wherein the reaction steps may take place at a temperature of about 0° C. to about 60° C. and about ambient pressure, wherein the ratio of the carboxylic acid to the glucose was from about 5:1 to about 50:1, and wherein the ratio of the glucose pentaester to the basic reagent was from about 1:50 to about 1:150.
OLIGONUCLEOTIDE SYNTHESIS ON SOLID SUPPORT
Functionalized solid supports are useful in the synthesis of oligonucleotides. The functionalized solid supports contain an extended linker to a terminal functional group or a first nucleotide or nucleoside moiety. The extended linker permits oligonucleotide synthesis to take place at a greater distance from the solid support with greater efficiency.

SAPONIN CONJUGATE AND VACCINE OR PHARMACEUTICAL COMPOSITION COMPRISING THE SAME
The present invention is directed to novel chemical compounds in which a lipophilic moiety such as a lipid, fatty acid, polyethylene glycol or terpene is covalently attached to a non-acylated or desacylated triterpene saponin via a carboxyl group present on the 3-O-glucuronic acid of the triterpene saponin. The attachment of a lipophile moiety to the 3-O-glucuronic acid of a saponin such as Quillaja desacylsaponin, lucyoside P, or saponin from Gypsophila, Saponaria and Acanthophyllum enhances their adjuvant effects on humoral and cell mediated immunity. Additionally, the attachment of a lipophile moiety to the 3-O-glucuronic acid residue of non- or des-acylsaponin yields a saponin analog that is easier to purify, less toxic, chemically more stable, and possesses equal or better adjuvant properties than the original saponin.
