  Cycloadditions of Mesitonitrile Oxide with Hydroxy- and Methoxy-substituted Stilbenes. A Directing Hydrogen Bonding Model

  摘要：

  The regioselectivity of the reaction of mesitonitrile oxide with o-hydroxystilbene in favour of the 5-(2-hydroxyphenyl) isomer (regioisomeric ratio 5:1) is accounted by a directing hydrogen bonding model, while for reactions of the p-hydroxy- and p-methoxystilbene which show a 2:1 ratio between the 5- and 4-regioisomer, an electron-donor effect is invoked. These phenomena of regioselectivity are supported by semiempirical AM1 calculations.
