Mazzeo, Giuseppe; Longhi, Giovanna; Abbate, Sergio; Palomba, Martina; Bagnoli, Luana; Marini, Francesca; Santi, Claudio; Han, Jianlin; Soloshonok, Vadim A.; Di Crescenzo, Emilio; Ruzziconi, Renzo published an article in 2017, the title of the article was Solvent-free, uncatalyzed asymmetric “ene” reactions of N-tert-butylsulfinyl-3,3,3-trifluoroacetaldimines: a general approach to enantiomerically pure α-(trifluoromethyl)tryptamines.Recommanded Product: 141940-37-6 And the article contains the following content:
A novel approach to regioselectively substituted and stereoselectively α-trifluoromethylated tryptamines, e.g., I [Y = H, Me-5, OMe-5, Cl-5, F-5, CF3-5 or CF3-6] and II, is reported based on the ene reaction of Boc-protected 3-methyleneindolines with optically pure (R)- or (S)-tert-butanesulfinyltrifluoroacetaldimine. Boc- and sulfinylamido-protected α-trifluoromethyltryptamines are obtained in 60-70% yield and 85/15 dr by just heating equimolar amounts of the two reaction partners at 80-90 °C for 2-3 h without a solvent. The absolute configuration of the amino α-carbon has been assigned based on the vibrational CD (VCD) spectral anal. The two protecting group can be chemoselectively removed allowing further regio- and stereoselective elaboration of the ene products to various biol. interesting compounds The experimental process involved the reaction of tert-Butyl (4-(trifluoromethyl)phenyl)carbamate(cas: 141940-37-6).Recommanded Product: 141940-37-6
