Abstract
Polystyrene-supported chiral 2,2′-methylenebis[(4S)-4-tert-butyl-2-oxazoline] is a promising heterogeneous catalyst for the enantioselective Henry reaction of nitromethane with substituted benzaldehydes. The process is carried out in ethanol as a green solvent, and the corresponding chiral β-nitroalcohols are obtained in 56–95 % yield with 49–88 % ee.| File | Dimensione | Formato | |
