摘要:
High, but not dry: A highly enantioselective Michael reaction in water has been developed by using a simple DNA-based catalyst. Enantioselectivities of up to 99% ee could be obtained by using nitromethane and dimethyl malonate as the nucleophiles and αf,β-unsaturated 2-acylimidazoles as the Michael acceptors. The reactions can be performed on a preparative scale and the catalyst can be recycled. (Chemical Equation Presented). © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
