摘要:
Nonmetallic, chiral organic catalysts are used to catalyze an enantioselective aldol coupling reaction between aldehyde substrates. The reaction may be carried out with a single enolizable aldehyde, resulting in dimerization to give a β-hydroxy aldehyde, or trimerization to give a dihydroxy tetrahydropyran. The reaction may also conducted with an enolizable aldehyde and a second aldehyde, which may or may not be enolizable, so that the coupling is a cross-aldol reaction in which the α-carbon of the enolizable aldehyde adds to the carbonyl carbon of the second aldehyde in an enantioselective fashion. Reaction systems composed of at least one enolizable aldehyde, an optional additional aldehyde, and the nonmetallic chiral organic catalyst are also provided, as are methods of implementing the enantioselective aldol reaction in the synthesis of sugars.
