摘要:
Proline was found to effectively mediate the asymmetric reaction of beta-ionylideneacetaldehyde 1A, retinal and related alpha,beta-unsaturated aldehydes to form their corresponding self-condensation products in reasonable enantiomeric excess (up to 65% ee). This same interesting conversion was also observed when 1A was incubated in the presence of the milk whey protein beta-lactoglobulin (BLG).
