An efficient asymmetric aerobic oxidation of tetrahydroisoquinolines with terminal alkynes was realized under mild reaction conditions using O2 as the sole oxidant. A chiral N,N′-dioxide/zinc(II)/iron(II) bimetallic cooperative catalytic system proves to be efficient for the formation of various α-alkynyl substituted tetrahydroisoquinolines in good to excellent yields and enantioselectivities.

A novel chiral organic contact ion-pair catalytic system has been developed for the transition-metal-free catalytic enantioselective oxidative cross-dehydrogenative coupling of tertiary amines to ketones for sp3 C–H functionalization. This new strategy provides an efficient and environmentally friendly way to access diversify optically active C1-alkylated tetrahydroisoquinoline derivatives from simple starting materials under mild conditions.

An organocatalysis/copper-catalyzed asymmetric oxidative sp(3) C-H olefination reaction of tertiary amines with olefins usingmolecularoxygen as the sole oxidant under mild conditions was realized for the first time. This novel strategy provides an efficient and environmentally friendly way to access diversify optically active C(1)-alkene tetrahydroisoquinoline derivatives.

A novel method for the synthesis of α-aminonitrile through visible-light-induced oxidative cyanation of N-aryltetrahydroisoquinoline with potassium thiocyanate has been developed. The process does not require the use of a photocatalyst, transition metal reagent, strong oxidizing agent, or toxic cyano-containing compound, which makes the reaction simple and green.
