STEREOSELECTIVITY OF CYCLOADDITIONS OF ARYLNITRILE OXIDES TO 5-ALKOXY-2(5H)-FURANONE
Fisera, Lubor,Oravec, Peter
, p. 1315 - 1324 (2007/10/02)
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
