Room Temperature Copper(II)-Catalyzed Oxidative Cyclization of Enamides to 2,5-Disubstituted Oxazoles via Vinylic C–H Functionalization
摘要:
A copper(11)-catalyzed oxidative cyclization of enamides to oxazoles via vinylic C-H bond functionalization at room temperature is described. Various 2,5-disubstituted oxazoles bearing aryl, vinyl, alkyl, and heteroaryl substituents could be synthesized in moderate to high yields. This reaction protocol is complementary to our previously reported iodine-mediated cyclization of enamides to afford 2,4,5-trisubstituted oxazoles.

applicable with a wide range of azabenzonorbornadienes and vinyl bromides under nickel/copper co-catalytic system, affording the cis ring-opening vinylation products in good yields with high optical purities. The present study has enabled straightforward stereoselectivepreparation of chiral 2-vinyl-tetrahydronaphthalens from vinyl halides.
