I found the field of Chemistry very interesting. Saw the article Allylation and alkylation of oxindoleketimines via imine umpolung strategy published in 2021.0. SDS of cas: 91-00-9, Reprint Addresses Shen, MH; Xu, DF (corresponding author), Changzhou Univ, Sch Pharm, Jiangsu Key Lab Adv Catalyt Mat & Technol, Changzhou 213164, Jiangsu, Peoples R China.. The CAS is 91-00-9. Through research, I have a further understanding and discovery of Diphenylmethanamine
When treated with an alkoxide base like t-BuOK in aprotic solvent, N-diphenylmethyl imino oxindoles, made conveniently through condensation of corresponding isatins with N-diphenylmethyl amine, are deprotonated to form azaallyl anions. Allylation and alkylation of this type of intermediates proceed smoothly with diverse C-electrophiles. Acidic work up finishes 3-amino-3-allyl/alkyl oxindoles. The overall transformation equals to an umpolung process at the C3 of isatins. (c) 2021 Chinese Chemical Society and Institute of Materia Medica, Chinese Academy of Medical Sciences.
