Application
An Efficient Chiral Organocatalyst for the Cross-aldol Reaction of Aliphatic Ketones with Aldehydes
An aldehyde (0.5 mmol) is added to a mixture of ketone (2 mmol) and Singh's catalyst (0.5 mol %) in brine (0.5 mL) at -5 °C. The reaction mixture is stirred and the progress of the reaction is monitored by TLC. After reaction is over, the reaction mixture is diluted with EtOAc (10 mL). The organic layer is separated and dried over anhydrous Na2SO4. It is purified over silica gel by column chromatography to give the aldol product.
