3-(Phosphorylmethylene)oxindoles have been prepared by a straightforward Horner-Wadsworth-Emmons reaction. They were treated with ethyl N-[(4-nitrophenyl)sulfonyl]oxy]-carbamate (NsONHC0 2 Et) in the presence of CaO to afford new aziridine-2-phosphonates spiro-fused with oxindole. 3-(Phosphorylmethylene)oxindoles were also transformed into novel spiro[oxindole-oxiranes] by reaction with H 2 O 2 /NaOH
3-(磷酸亚甲基)羟吲哚已通过简单的 Horner-Wadsworth-Emmons 反应制备。在CaO存在下用N-[(4-硝基苯基)磺酰基]氧基]-氨基甲酸乙酯(NsONHCO 2 Et)处理它们以提供新的氮丙啶-2-膦酸酯与羟吲哚螺稠合。通过与 H 2 O 2 /NaOH 反应,3-(磷酰基亚甲基) 羟吲哚也转化为新型螺[羟吲哚-环氧乙烷]。
