Two-phase reaction of a two-component molecular crystal of 2-naphthol and 2-naphthylamine suspended in aqueous Fe3+ solutions gives a cross-coupling product, 2-amino-2′-hydroxy-1,1′-binaphthalene, with good selectivity.

A facile and efficient protocol for the synthesis of 2'-functionalized 1,1'-binaphthyl-2-ols has been developed. The C,O-dilithio reagent (2) generated by the reductive ring-opening of binaphthofuran (1) with lithium was treated with the corresponding electrophiles to give 2'-functionalized 1,1'-binaphthyl-2-ols including the halides (3), amine (4), acid (5), aldehyde (6), carbonate (7) or phosphonate (8), respectively, in moderate to good yields.

A practical synthesis of 2-amino-2′-hydroxy-1,1′-binaphthyl (NOBIN) was realized from BINOL through a single step. Its facile purification procedure makes the process amenable for large scale synthesis of NOBIN.

Bianthryl-based organocatalysts for the asymmetric Henry reaction of fluoroketones

We have developed a catalytic system based on bianthrylbis(thiourea) for the asymmetric Henry reaction of fluoroketones and nitroalkanes that resulted from the screening of a library containing 31 chiral non-racemic organocatalysts. The corresponding adducts were isolated in up to 6 times shorter reaction time in comparison with the previously published organocatalysts. High levels of stereocontrol have been generally observed, with measured product enantiomeric excesses up to 97% and diastereomeric ratio 3:2 (anti/syn). The above-mentioned catalysts have been successfully applied to the total asymmetric synthesis of CF3-tethered (S)-halostachines, which has proved that this method constitutes an easy entry to similar enantiopure compounds.
