Zhou, Mingwei published the artcileZinc triflate-mediated cyclopropanation of oxindoles with vinyl diphenyl sulfonium triflate: a mild reaction with broad functional group compatibility, Application of 5,6-Dichloroindolin-2-one, the main research area is spirocyclopropyloxindole preparation; oxindole vinyl diphenyl sulfonium triflate zinc triflate mediated cyclopropanation.
The first use of zinc triflate for the cyclopropanation of unprotected oxindoles with vinyl di-Ph sulfonium triflate salt to afford spiro[cyclopropane-1,3′-indoline]-2′-ones I [R = 5-OH, 6-F, 7-Cl, 4-Br, etc.] was reported. The reaction proceeded under ambient conditions and consistently provided high yields with broad functional group tolerability. The utility for the late-stage functionalization (LSF) of complex mols. was demonstrated.
RSC Advances published new progress about Cyclopropanation. 71293-59-9 belongs to class indole-building-block, name is 5,6-Dichloroindolin-2-one, and the molecular formula is C8H5Cl2NO, Application of 5,6-Dichloroindolin-2-one.
