Enantioselective copper-catalyzed 1,4-addition of dialkylzincs to enones followed by trapping with allyl iodide derivatives

, p. 640 - 647 (2011/08/06)
Enantioselective copper-catalyzed 1,4-addition of dialkylzincs to enones proceeded in the presence of 0.1 mol% of Cu(OTf)2 and 0.25 mol% of an N,N,P-ligand containing a quinoline moiety to afford the corresponding conjugated adducts in 99%ee. The intermediate zinc enolates were trapped with substituted allyl iodides to give disubstituted ketones with high diastereoselectivity and enantioselectivity.
Synthesis of 2,2c-6-trisubstituted and 2,2c-,6,6--tetrasubstituted diaryl sulfides and diaryl sulfones by copper-promoted coupling and/or ortholithiation

Stoichiometric copper(I) iodide, in the presence of potassium carbonate and ethylene glycol, promotes the coupling of even highly sterically encumbered 2,6-disubstituted thiophenols and aryl iodides to form hindered diarylsulfides. Hindered diarylsulfones
Phenylthiyl radical complexes of gallium(III), iron(III), and cobalt(III) and comparison with their phenoxyl analogues

Three hexadentate, asymmetric pendent arm macrocycles containing a 1,4,7-triazacyclononane-1,4-diacetate backbone and a third, N-bound phenolate or thiophenolate arm have been synthesized. In [L1]3- the third arm is 3,5-di-tert-butyl
