COA of Formula: C7H9NO2SIn 2019 ,《Stereoinversion of Unactivated Alcohols by Tethered Sulfonamides》 appeared in Angewandte Chemie, International Edition. The author of the article were Marcyk, Paul T.; Jefferies, Latisha R.; Abu Salim, Deyaa I.; Pink, Maren; Baik, Mu-Hyun; Cook, Silas P.. The article conveys some information:
A simple iron-based catalyst system for the mild, direct conversion of secondary and tertiary alcs. to sulfonamides was described. Starting from enantioenriched alcs., the intramol. variant proceeded with stereoinversion to produced enantioenriched 2- and 2,2-subsituted pyrrolidines I [R = Me, n-Pr, i-Bu, 4-MeOC6H4] and indolines II [R1 = i-Bu, n-hexyl, CH2(4-MeOC6H4), etc.; Y = H, F, MeO, CF3], without prior derivatization of the alc. or solvolytic conditions. In addition to this study using 4-Methylbenzenesulfonamide, there are many other studies that have used 4-Methylbenzenesulfonamide(cas: 70-55-3COA of Formula: C7H9NO2S) was used in this study.
4-Methylbenzenesulfonamide(cas: 70-55-3) belongs to anime. In organic chemistry, amines are compounds and functional groups that contain a basic nitrogen atom with a lone pair. Amines are formally derivatives of ammonia (NH3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group (these may respectively be called alkylamines and arylamines; amines in which both types of substituent are attached to one nitrogen atom may be called alkylarylamines).COA of Formula: C7H9NO2S
