标题:Regio-And Stereocontrol In The Intramolecular Nitrile Oxide Cycloaddition To 2-Furylthiol-And 2-Furylmethanethiol Derivatives.
摘要:A Series Of 2-Furyl And 2-Furylmethyl Substituted Nitrosulphides With A Proper Chain Length Were Prepared And Showed To Undergo A Totally Regiocontrolled Intramolecular Furan-Nitrile Oxide Cycloaddition To Give Cis-Fused Products In High Yield. Insertion Of A Stereocenter On The Cycloaddends Did Not Allow Satisfactory Control Of The Absolute Stereochemistry Of The Reaction. Enantiomerically Enriched Products (E.E. Less-Than-Or-Equal-To 95%) Were Obtained By A Kinetic Resolution Process Involving Oxidation Of The Sulphide Cycloadducts To The Corresponding Sulphoxides.
