Abstract

The investigation sought to determine whether a transition metal coupling reaction with aryl halides could be utilized to form glycoconjugates, carbohydrate-containing molecules, specifically C-Aryl Glycosides. Our successful novel application in glycochemistry employs the Stille coupling reaction and improves the viability of accessing a range of glycogonjugates for biological and therapeutic screening.(¹) The reaction maintains exceptional retention of configuration from the carbohydrate-metal bond in the completed sp³ carbon – sp² carbon bond of the produced glycoside. A synthesized library of C-aryl Glycosides was established utilizing this methodology; from which a selective schema was submitted for publication. This technology provides a route to discrete carbohydrate building blocks that can be assembled with minimal reagents and moderate synthetic knowledge. These building blocks can then be stereo-specifically attached to molecules of interest under a set of general catalytic conditions; expediting the investigation of carbohydrate’s role in biochemical processes that was limited by substrate dependent laborious processes of glycoconjugate formation.
