资源简介：
The Hauser–Kraus annulation of sulfonylphthalide with 3-olefinic oxindole has been performed. This strategy, which involves a cascade Michael addition–Dieckmann cyclization–elimination sequence, offers rapid and convenient access to novel spiro-dihydronaphthoquinone-oxindoles in excellent yields with complete selectivity for the enolic form under mild reaction conditions.
