The reaction efficiently progressed, which gave the desired spiro[cycloalkane-1,3’-indoline]-2,2’-diones in high to quantitative yields. The easy conversion of the carbonyl functional group of the obtained spiroindolinone was also demonstrated. https://www.thieme-connect.com/products/ejournals/abstract/10.1055/s-0037-1611563 Thime 2019-06-24 eng other AO http://hdl.handle.net/2298/00031533 https://kumadai.repo.nii.ac.jp/records/31546 10.1055/s-0037-1611563 00397881 Synthesis 51 17 3277 3286 https://kumadai.repo.nii.ac.jp/record/31546/files/SynthesisSynthesis.2019,51(17),3277-3286-supporting+info.pdf application/pdf 11.4 MB 2020-08-25 https://kumadai.repo.nii.ac.jp/record/31546/files/Synthesis.2019,51(17),3277-3286.pdf application/pdf 201.3 kB 2020-08-25
