The regio- and stereoselectivity of the [4 + 2] cycloaddition of maleic, citraconic, dichloromaleic, and dibromomaleic anhydrides to difurfuryl amines and secondary furfurylamines were studied. N-Furfuryl-, N-phenyl-, and N-benzylhexahydrooxoepoxyisoindole-7-carboxylic acids were synthesized. An approach was developed for obtaining hexahydroepoxyoxoisoindole-7-carboxylic acid unsubstituted at the nitrogen
研究了马来酸酐,柠康酸酐,二氯马来酸酐和二溴马来酸酐与[4 + 2]环加成反应对二糠胺和仲糠胺的区域和立体选择性。Ñ -Furfuryl-,Ñ苯基,和Ñ -benzylhexahydrooxoepoxyisoindole -7-羧酸合成的。开发了一种获得在氮原子上未取代的六氢环氧氧代异吲哚-7-羧酸的方法。二卤代环氧异吲哚酮羧酸的氧杂环庚烯片段的芳构化得到一系列的7-羧基-2-R-异吲哚-1-酮。
