Iron-Catalyzed Oxidative C(3)–H Functionalization of Amines
摘要:
Fe-catalyzed direct dehydrogenative C(3)-functionalization of tertiary arylamines was developed via activation of the sp(3) C(3)-H bond. The reaction is applicable to both cyclic and acyclic amines. The key process is the catalytic desaturative enamine formation from tertiary amines and position-selective C-C bond formation (addition to nitro olefins) at the beta-carbon. Products can be converted to versatile and unique nitrogen-containing molecules.

selectivity previously reported for B(C6F5)3-catalyzed C(sp3)–H alkylation of tertiary amines with electron-deficient olefins remains a mystery. The selectivity appears to be governed by the number of electron-withdrawing groups (EWGs) on the olefin: one EWG results in α-alkylation, whereas two EWGs (one on each end of the double bond) result in β-alkylation. In this study, we solved the mystery and unlocked
