  (S)-Threonine/α,α-(S)-diphenylvalinol-derived chiral ionic liquid: an immobilized organocatalyst for asymmetric syn-aldol reactions

  摘要：

  Chiral ionic liquids containing (S)- or (R)-threonine amide and alpha,alpha-(S)-diphenylvalinol units were synthesized In the presence of the (S)-threonine-derived catalyst reactions between ketones with secondary carbon atom(s) at the alpha-position with respect to the carbonyl group and aromatic (heteroaromatic) aldehydes afforded the corresponding syn-aldols in high yields (up to 99%) and with high diastereo-(syn/anti up to 97:3) and enantioselectivity (up to 99% ee), which was maintained over three reaction cycles.

  amino acids covalently supported onto polystyrene through alkyne–azide cycloaddition reactions has been synthesized and evaluated as catalysts in asymmetric aldol reactions. A polymer‐supported threonine behaves as an easily recyclable, highly reactive and stereoselective (up to 99% ee) catalyst in the aldol reaction of both cyclic and acyclic ketone donors with aromatic aldehydes in aqueous environments

  Two new organocatalysts 3a and 3b, derived from L-leucine and (S)-beta-amino alcohols that were prepared from L-valine, were designed and afforded the direct syn-aldol reactions of a wide scope of aldehydes with various ketones with an excellent diastereomeric ratio of up to >20/1 and enantioselectivities of up to 99% ee.
