onic acidderivatives has been described. Reaction of (4-methyl-3,5-dinitrophenyl)phosphonates with dimethylformamide dimethyl acetal leads to the respective enamines that can be readily converted into indoles by the Batcho–Leimgruber synthetic protocol. Proper choice of reducing agent for the reductive cyclization of intermediate enamines allows to selectively obtain (4-nitro-1H-indol-6-yl)- and
已经描述了合成先前未报道的(1 H-吲哚-6-基)膦酸衍生物的方便方法。(4-甲基-3,5-二硝基苯基)膦酸酯与二甲基甲酰胺二甲基乙缩醛反应生成相应的烯胺,可通过Batcho-Leimgruber合成方案将其轻松转化为吲哚。还原剂中间体烯胺的还原性环化的合适的选择,允许选择性地得到(4-硝基- 1 H ^ -吲哚-6-基) -和(4-氨基- 1 H ^ -吲哚-6-基)膦酸酯。
