A FACILE SYNTHESIS OF 3-GLYCOSYL-5-SUBSTITUTED-2-ISOXAZOLES
摘要:
The 1,3-dipolar cycloaddition reaction between a 2-deoxy-D-aldose Mime (D-gluco or D-ribo) and an alkyne as dipolarophile (phenylacetylene, 2-propyn-1-ol, 3-chloro-1-propyne, or 3-bromo-1-propyne) is described. The new 3-glycosyl-5-substituted-2-isoxazoles are characterized physically and spectroscopically.
