  Synthesis and resolution of 1-(2-diphenylphosphino-1-naphthyl)isoquinoline; a PN chelating ligand for asymmetric catalysis.

  摘要：

  A multistep synthesis resulting in a good yield of the title compound has been developed based on the Pd-catalysed coupling of 1-chloroisoquinoline and 2-methoxy-1-naphthylboronic acid (5). The product is converted into the corresponding tfifluoromethanesulphonate (10) by successive demethylation and treatment with (CF3CO)2O, followed by a further Pd-catalysed coupling with Ph2P(O)H. The resulting phosphine oxide (11) was cleanly reduced with HSiCl3. Resolution of the phosphinamine (4) was carried out with the Pd complex derived from (R)-(+)-dimethyl(1-(1-naphthyl)ethyl)amine and PdCl2; the diastereomers were of different stabilities and solubilities and were therefore readily separated. The resolved phosphinamine, [alpha]D22 +/- 153 (c = 1, CHCl3), was enantiomerically stable on heating to 65-degrees-C for 24h. X-ray crystal structures of the adduct (16) and the Pd dimer (7) isolated during the initial coupling reaction are presented.

  日期：——

  An equivalent amount of N-heteroaryl and aryl Grignard or lithium reagents, after mediation by an equivalent of titanate, was facilely coupled to furnish N-heteroaryl-aryl compounds under the catalysis of FeCl3/TMEDA at ambient temperature using oxygen as an oxidant. Most of the common N-heteroaryls were all good candidates, and thus provided a general, green and pratical protocol for the flexible

  Allylation of aromatic aldehydes 1a-m with allyl- and crotyl-trichlorosilanes 2- 4, catalyzed by the chiral N-oxide QUINOX (9), has been found to exhibit a significant dependence on the electronics of the aldehyde, with p-(trifluoromethyl)benzaldehyde 1g and its p-methoxy counterpart 1h affording the corresponding homoallylic alcohols 6g, h in 96 and 16% ee, respectively, at -40 degrees C.

  heterocyclic analogues can be efficiently prepared by palladium-catalysed cross-coupling reactions between tri(1-naphthyl)indium reagents and 1-halonaphthalenes and haloisoquinolines. The reactions were usually carried out in THF at 80 °C with a slight excess of the indium reagent (40 mol-%) and a low catalyst loading (4 mol-% Pd) to afford the cross-coupling products in good yields (45–99 %). The method allows

  The synthesis of bridged dimeric isoquinolylnaphthols has been developed. A simple method for the resolution of 1,1′-isoquinolyl-2′-naphthol permits measurement of the optical stability of the monomer, and in several cases slow racemisation at ambient temperature was observed. The enantiomeric stability is not greatly affected by steric buttressing. An unusual enhancement of the rate of atropisomerism
