Enantioselective, Lewis Base-Catalyzed, Intermolecular Sulfenoamination of Alkenes

Abstract: A method for the catalytic, enantioselective, intermolecular, 1,2-sulfenoamination of alkenes is described. Functionalization is achieved through the intermediacy of an enantioenriched, configurationally stable thiiranium ion generated by Lewis base activation of a readily available sulfur electrophile. A diverse set of anilines and benzylamines react with different styrenes to afford products in good yield and stereoselectivity. Downstream manipulation of the products is facilitated by deprotonation of the am… Show more

“…Theu tility of the polyene cyclization is illustrated in the enantioselective,t otal syntheses of two natural products: (+ +)-ferruginol (59)and (+ +)-hinokiol (60)(Scheme 27). Prior total syntheses were achieved either by ad iastereoselective cyclization or from chiral pool starting materials.The polyene cyclization starts with unsymmetrically substituted 58 which under typical reaction conditions is transformed to common intermediate (+ +)-57 d as as ingle constitutional isomer.…”

“…of thiiranium ions by anilines and benzylamines. [59] Design of Experiment (DoE) optimization [60] revealed an important interplay of the stoichiometry of each of the reagents; specifically,d irect sulfenylation of the nucleophile is found to interfere with the reaction. Scheme 38 shows electronically diverse anilines as competent nucleophiles to forge 1,2-amino sulfides in good yield and excellent enantioselectivity (77 ad).…”

“…[53] In Gegenwart des Lewis-basischen Sele Ein wichtiger Fortschritt in der Sulfenoaminierung wurde 2019 von Denmark und Roth fürd en intermolekularen Abfang von Thiiraniumionen durch Aniline und Benzylamine vorgestellt. [59] Die Optimierung des Versuchsplans (DoE) [60] zeigte ein wichtiges Zusammenspiel der Stçchiometrie jedes der Reagentien;i nsbesondere wurde festgestellt, dass die direkte Sulfenylierung des Nukleophils die Reaktion stçrt.
