The best method to prepare unequivocally and in good yields β-acetylenic, α-acetylenic and α-allenic tertiary amines RR′CHNR″2 (R unsaturated group, R′, R″ alkyl groups) from immonium salts has been evaluated.
Efficient and General Aerobic Oxidative Cross-Coupling of THIQs with Organozinc Reagents Catalyzed by CuCl<sub>2</sub>: Proof of a Radical Intermediate
general new method for the highly concise synthesis of C-1-alkylated tetrahydroisoquinolines (THIQ) is reported. The CuCl2-catalyzed procedure is based on a coupling of nonfunctionalized THIQs with organozincreagents under aerobic conditions. It proceeds in high yields and is broadly applicable to a wide range of substrates. It relies on a regioselective sp3 C–H bond activation allowing for an sp3–sp3

Two darts in the middle! This work reports the doubleaddition of propargylzincreagents to nitriles (acylcyanohydrins and cyanocarbonates). This methodology provides a straightforward access to dipropargylic α,α-disubstituted hydroxyamides or N-Boc-protected amino alcohols which can be converted into functionalized pyridine derivatives after cobalt-catalyzed [2+2+2] cycloaddition reactions involving
