Recently I am researching about ENANTIOSELECTIVE CONSTRUCTION; AMIDES; NITRILES; ALCOHOLS; ESTERS; ACTIVATION; HYDRATION; VERSATILE; ISATIN, Saw an article supported by the JSPS KAKENHI from the Japan Society for the Promotion of Science (JSPS)Ministry of Education, Culture, Sports, Science and Technology, Japan (MEXT)Japan Society for the Promotion of ScienceGrants-in-Aid for Scientific Research (KAKENHI) [17H01341, 18K14051, 18K14057, 19K05556]; Japanese Ministry of Education, Culture, Sports, Science, and Technology (MEXT)Ministry of Education, Culture, Sports, Science and Technology, Japan (MEXT); JST-CRESTJapan Science & Technology Agency (JST)Core Research for Evolutional Science and Technology (CREST) [JPMJCR17J3]. COA of Formula: C8H7NO. Published in SCIENCE PRESS in BEIJING ,Authors: Rashed, MN; Touchy, AS; Chaudhari, C; Jeon, J; Siddiki, SMAH; Toyao, T; Shimizu, K. The CAS is 59-48-3. Through research, I have a further understanding and discovery of Indolin-2-one
We report herein that a commercially available CeO2 is an active and reusable catalyst for the C3-selective alkenylation of oxindole with aldehydes under solvent-free conditions. This. catalytic method is generally applicable to different aromatic and aliphatic aldehydes, giving 3-alkyledene-oxindoles in high yields (87%-99%) and high stereoselectivities (79%-93% to E-isomers). This is the first example of the catalytic synthesis of 3-alkenyl-oxindoles from oxindole and various aliphatic aldehydes. The Lewis acid-base interaction between Lewis acid sites on CeO2 and benzaldehyde was studied by in situ IR. The structure-activity relationship study using CeO2 catalysts with different sizes suggests that defect-free CeO2 surface is the active site for this reaction.
