Regio- and stereospecific syntheses of several spiro[pyrrolidine2,3′-oxindole] derivatives by cycloaddition trapping of azomethine ylides generated in situ, via decarboxylative condensation of isatin with α-amino acids or by reaction of secondary amines with isatin, are reported. 2,6-Dibenzylidenecyclohexanone, 2-arylidene-1-tetralone, and arylidenemalononitrile derivatives have been efficiently used
据报道,通过环加成捕获原位生成的偶氮甲碱叶立德,通过靛红与 α-氨基酸的脱羧缩合或仲胺与靛红的反应,区域和立体有择合成了几种螺[吡咯烷 2,3'-羟吲哚] 衍生物。2,6-二亚苄基环己酮、2-亚芳基-1-四氢萘酮和亚芳基丙二腈衍生物已被有效地用作捕获偶极体。添加物的区域和立体化学受前沿轨道和空间相互作用控制。© 2002 Wiley Periodicals, Inc. 杂原子化学 13:324–329, 2002; 在线发表于 Wiley Interscience (www.interscience.wiley.com)。DOI 10.1002/hc.10038
