概要

• 論文の詳細を見る

• 1-Alkyl-2,1-benzisoxazolium salts were prepared by the reaction of 2,1-benzisoxazoles with trialkyl orthoformates in the presence of Lewis acids as well as with Meerwein's reagents or dialkoxycarbonium hexachloroantimonates. Reactions of these quarternary salts with various nucleophilic reagents afforded 3-substituted 1-alkyl-2,1-benzisoxazoline derivatives.
