日期:2006.1.1
The asymmetric, catalytic addition of terminal alkynes to discrete alkyliminium species in the presence of copper bromide, QUINAP ligand, and triethylamine is reported. The reaction proceeds in high yield and high enantiomeric excess with a variety of substrates in solution and is also amenable to solid-phase synthesis.

Total synthesis of racemic 1-aryl-tetrahydroisoquinoline alkaloids
AbstractA new synthetic route was developed for the preparation of natural products cryptostyline I, II, III and 1-phenyl-6,7-dimethoxy-2-methyl-1,2,3,4-tetrahydroisoquinoline. The Liebeskind–Srogl palladium-catalyzed carbon–carbon cross-coupling protocol was used in the key step of the totalsynthesis. Graphical abstract
