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.
