摘要
2,3,4,6-四- O -乙酰-g - d - glucopyranoyl异硫氰酸酯的C=S双键在[3+2]环加成下与1-氮杂-2-氮杂二烯盐反应生成(葡萄糖基)-1,3,4-噻二唑。
One-pot synthesis of N -nucleosides via 1,3-dipolar cycloaddition of 1-aza-2-azoniaallene salts to 2,3,4,6-tetra- O -acetyl-β-D-glucopyranosyl isothiocyanate\
The C=S double bond of 2,3,4,6-tetra- O -acetyl- g -D-glucopyranosyl isothiocyanate reacts with 1-aza-2-azoniaallene salts under [3+2] cycloaddition to afford (glucosylimino)-1,3,4-thiadiazoles.
