Acylglucoses have been shown to be an effective deterrent of tomato pests including green peach aphids, potato aphids, silverleaf whiteflies, and many others. These acylglucose mixtures are naturally produced and secreted by the <i>Solanum pennellii</i>, a wild tomato species that exhibits insect resistance. Hybridization of this tomato species with others produce the acyl sucrose that has additionally shown potential in greenhouse pest management. Previous research has developed synthetic pathways to synthesize the 2,3,4-triesterified monosaccharides. Taking this knowledge, work began on the total synthesis of polyesterified sucrose through a three-step process: Protection of the primary alcohols, esterification of the remaining alcohols, and deprotection of the primary silyl ethers. Future work includes testing of the acyl sucrose to compare with the acylglucose on the previously mentioned pests in greenhouse and high tunnels.
