Pyrrole and indole derivatives react with benzenesulphonylcarbonitrile oxide, 1 (BSNO) generated in situ to give sulphonyl oximes without isolable isoxazoline intermediates.Furan reacts with BSNO to give isoxazoline 5b; treatment with acid affords the corresponding oxime 2b.Reduction of the sulphonyl oximes with aqueous titanium(III) chloride gives nitriles.The sulphonyl oxime 7 derived from indole reacts with tri-n-propylamine and stilbene to give isoxazoline 10.
