موضوع انگلیسی:Synthesis of “Click BOX” ligands and preliminary results on their
application in the asymmetric copper catalysed Henry reaction
of o-methoxybenzaldehyde
بخشی از متن:Two new chiral “click BOX” ligands have been synthetised with high yields starting from commercially available
dimethyl propargylmalonate and optically pure alkanolamines, followed by copper catalysed cycloaddition
(CuAAC) and oxazoline ring formation. Catalytic activity of the new ligands has been tested in the
copper mediated Henry addition. The model reaction between nitromethane and o‐anisaldehyde affords the
related 1‐(2‐methoxyphenyl)‐2‐nitroethanol in high yields (up to 92%) and moderate enantioselectivities
(up to 67% e.e.) under straightforward experimental conditions
