5,6-Difluoroindolin-2-one (cas: 71294-07-0) belongs to indole derivatives. Indole produced by Proteus, Pseudomonas, Escherichia and other species was shown to be a growth promoting factor in Arabidopsis thaliana. In addition to indole, the strain-release chemistry worked for numerous substrates including amines, alcohols, thiols, carboxylic acids, imidazoles, and pyrazoles.Computed Properties of C8H5F2NO

Highly Enantioselective Synthesis of Spiro[cyclohexanone-oxindoles] and Spiro[cyclohexanone-pyrazolones] by Asymmetric Cascade [5+1] Double Michael Reactions was written by Wu, Bin;Chen, Jian;Li, Mei-Qiu;Zhang, Jin-Xin;Xu, Xiao-Ping;Ji, Shun-Jun;Wang, Xing-Wang. And the article was included in European Journal of Organic Chemistry in 2012.Computed Properties of C8H5F2NO This article mentions the following:

The construction of spiro compounds through cascade [5+1] double Michael reactions between divinyl ketones and N-unprotected oxindoles or N-phenyl-protected pyrazolones catalyzed by a combination of the easily available 9-amino-9-deoxy-epi-quinine with N-Boc-D-phenylglycine. The desired multistereogenic spiro[cyclohexanone-oxindoles] and spiro[cyclohexanone-pyrazolones] were obtained with high yields (up to 98 %) and stereoselectivities (up to >20:1 dr, 99 % ee). In the experiment, the researchers used many compounds, for example, 5,6-Difluoroindolin-2-one (cas: 71294-07-0Computed Properties of C8H5F2NO).
