摘要：
The 1,3 dipolar cycloadditions of diazomethane and ethyl diazoacetate with differently substituted 5-sulfur-2(5H)-furanones (1-6) are reported. Cycloaddition of diazomethane occurs in a regio- and stereospecific manner to give the expected adducts 9-14, in good yield The cycloaddition with ethyl diazoacetate occurs also in a regio- and stereospecific manner, but affords the corresponding 2-pyzolines 15-19.
