, p. 1307 - 1316 (2007/10/02)
The 1,3-dipolar cycloadditions of aceto-, benzo- and bromoformonitrile oxides to cyclic and open-chain 4-oxobut-2-enoic acid derivatives have been investigated.The addition to 5-methoxyfuran-2(5H)-one (1) gave regioselectively 3-substituted 6-exo-methoxy-
STEREOSELECTIVITY OF CYCLOADDITIONS OF ARYLNITRILE OXIDES TO 5-ALKOXY-2(5H)-FURANONE

1,3-Dipolar cycloaddition of arylnitrile oxides to 5-alkoxy-2(5H)-furanones (II) and 5-hydroxy-2(5H)-furanone leads regiospecifically to 4-oxo-3a,4,6,6a-tetrahydrofuroisoxazole derivatives IIIa-IIIj.The alkoxy derivatives give exclusively products
