A set of six solid-supported diarylprolinol catalysts (varying on the anchoring strategy and the type of polymeric support) has been prepared and applied to the enantioselective cyclopropanation reaction. The selected candidate allows implementation of a long flow experiment (48 h) and generates a library of 12 cyclopropanes by sequential flow experiments. The mildness and utility of the method have enabled a telescoped process in which the outstream is directly used in a Wittig flow reaction.
Superparamagnetic nanoparticle-Supported (S)-diphenyl- prolinol trimethylsilyl ether as a recyclable catalyst for asymmetric Michael addition in water

A new superparamagnetic nanoparticle-supported (S)-diphenylprolinol trimethylsilyl ether (Jorgensen-Hayashi catalyst) was synthesized and applied for the asymmetric Michael addition of aldehydes to nitroalkenes in water, which gives products in moderate t
