Spiro[indoline-3,2'-pyrrolidine] derivatives were prepared from β-3-indolyl ketone oximes by treatment with methanesulfonyl chloride and triethylamine via the bond formation between 3-position of the indole ring and oximenitrogen. These diazaspirocycles were readily transformed to the corresponding spiro oxindole derivatives.
螺[indoline-3,2'-pyrrolidine]衍生物是由β-3-吲哚基酮肟通过用甲磺酰氯和三乙胺通过吲哚环的3-位和肟氮之间的键形成来制备的。这些二氮杂螺环很容易转化为相应的螺羟吲哚衍生物。
