Guo, Ya-Ning
, p. 3762 - 3764 (2013)
A new Schiff base 2-[(3-bromo-phenylimino)methyl]phenol, derived from condensation of salicylaldehyde with m-bromoaniline, has been prepared and characterized by single crystal X-raydiffraction. Schiff base is in the monoclinic system, space group P21 with a = 3.928(14) ?, b = 10.590(4)?, c = 13.212(5)?, b = 97.360(4)?, Mr = 276.13, V = 545.1(3)?3, Dc = 1.682 g/cm3, Z = 2, μ = 3.745 mm-1, F(000) = 276, R = 0.0326, wR = 0.0455. The schiff base is stabilized by intermolecular C-H...O and p...p interaction and further linked into a 2D layer structure.
Copper-Catalyzed Asymmetric Annulation Reactions of Carbenes with 2-Iminyl- or 2-Acyl-Substituted Phenols: Convenient Access to Enantioenriched 2,3-Dihydrobenzofurans

We have developed a method for the highly diastereo- and enantioselective construction of 2,3-dihydrobenzofurans bearing tetrasubstituted carbon stereocenters by means of annulation reactions between carbenes and 2-iminyl- or 2-acyl-substituted phenols through catalysis by readily accessible copper(I)/bisoxazoline catalysts under mild conditions. These reactions feature a unique mechanism in which the copper catalyst serves a dual function: first it reacts with the diazo compound to generate a metal carbene, and second, upon formation of an oxonium ylide, it acts as a Lewis acid to activate the imine or ketone for diastereo- and enantioselective cyclization.
