The synthesis of glycoconjugates is of interest in biological and medicinal research. There are numerous approaches to the synthesis of glycosides involving protecting group free methods. This thesis outlines what has been achieved in the field and two novel approaches for O-glycosidation. The first approach involves the use of a toluenesulfonohydrazide glycoside with a purification handle designed for simple glycoside purifications. The butyl 3-O-octyl-D-glucopryanoside was successfully synthesized but did not have the desired property of yielding simple-to-purify glycosides as products. The second approach uses a thiouronium glycosyl donor; a variety of glycosidations using this donor were investigated. The glucosyl thiouronium salt donor was shown to undergo glycosidation effectively with simple alcohols.
