Resumo: |
Two strategies were considered for the synthesis of 2,3-unsaturated O-glucosyl-1,2,3-triazoles. The reaction between tri-O-acetyl-D-glucal and triazole alcohols gave no stereoselectivity. In fact, β-isomer formation was increased. A second strategy furnished 2,3-unsaturated O-glucosides from tri-O-acetyl-D-glucal and alkynols via Ferrier rearrangement; this methodology employing montmorillonite K-10 doped with FeCl3∙6H2O affords new glycosides in good to excellent yields, short time and high α-stereoselectivity in dichloromethane. Subsequently, the glucosides were coupled with 2-azido-1,4-naphthoquinone to give a new series of 1,2,3-1H-triazolyl O-glucoside derivatives based on click reaction. |
