Synthesis of 1,3-dioxacyclan-2-yl-substituted 1,2,3-triazoles
摘要:
A new method for preparing 4-(1,3-dioxacyclan-2-yl)-5-phenyl-1,2,3-triazoles in 30-75% yields has been developed on the basis of azide-alkyne cycloaddition to 2-phenylethinyl-1,3-dioxacyclanes. It has been shown that the best results are achieved when the reaction is carried out at 150-155A degrees C in DMSO.
