Guo, Qihang published the artcileControllable Intramolecular Unactivated C(sp3)-H Amination and Oxygenation of Carbamates, Category: esters-buliding-blocks, the publication is Organic Letters (2019), 21(4), 880-884, database is CAplus and MEDLINE.
Dual catalyst-controlled intramol. unactivated C(sp3)-H amination and oxygenation of carbamates merging visible-light photocatalysis and earth-abundant transition metal catalysis have been reported. Useful amino alc. and diol derivatives could be selectively obtained from readily available tertiary alc. derivatives The possible mechanisms have been proposed via a 1,5-HAT process followed by Lewis acid-controlled cyclization. The nickel and zinc catalysts inhibit the formation of oxygenation and amination products, resp. An interesting phenomenon of chirality transfer is also observed
