Enantioselective Oxidative Biaryl Coupling Reactions Catalyzed by 1,5-Diazadecalin Metal Complexes
摘要:
Chiral 1,5-diaza-cis-decalins have been examined as ligands in the enantioselective oxidative biaryl coupling of substituted 5-naphthol derivatives. Under the optimal conditions employing a 1,5-diaza cis-decalin copper(l) iodide complex with oxygen as the oxidant, rapid and highly selective couplings could be achieved (90-93% ee, 85% yield).
Disclosed herein are reversible and irreversible inhibitors of Bruton's tyrosine kinase (Btk). Also disclosed are pharmaceutical compositions that include the compounds. Methods of using the Btk inhibitors are described, alone or in combination with other therapeutic agents, for the treatment of autoimmune diseases or conditions, heteroimmune diseases or conditions, cancer, including lymphoma, and inflammatory diseases or conditions.

stereoelectronics and steric effects in controlling the equilibrium of substituted 1,5-diaza-cis-decalins. In the present study, N,N'-diethyl- and N,N'-bistrifluoroethyl-1,5-diaza-cis-decalins have been synthesized, and the equilibrium mixtures have been measured using 1H and 13C NMR experiments. Steric effects appear to control the equilibria between the two conformational isomers of 1,5-diaza-cis-decalin

5-diaza-cis-decalin Cu(II) complexes have been obtained. The amine substitution determines the type of copper coordination complex formed. For the secondary amine compound, 1,5-diaza-cis-decalin, 2:1 diamine:coppercomplexes appear to be the thermodynamically favored forms, but they are not catalytically active. Crystals of a catalytically competent trimeric 1:1 diamine:coppercomplex containing bridging

[GRAPHICS]A short, efficient synthesis of chiral 1,5-diaza-cis-decalins (7) is presented. In the lithiation of N-Boc pyrrolidine, the ligands with the smallest most electron rich R groups (Me > Et > (CH2Bu)-Bu-t > CH2CF3 approximate to Bn) were most effective. In the asymmetric deprotonation/substitution of benzylic substrates, (R,R)-7 (R = Me, R' = H) conferred modest selectivity. The ready availability of both enantiomers of the 1,5-diaza-cis-decalins and the ability to tune steric and electronic properties renders these compounds an attractive new class of diamine ligands.
