Highly diastereoselective reduction and addition of nucleophiles to binaphthol-protected arylglyoxals
摘要:
Arylglyoxals, protected at the aldehyde function with 1,1'-binaphthalene-2,2'-diol, are readily prepared by direct nucleophilic substitution of binaphthol-sodium salt on dibromoacetophenone and react highly diastereoselectively with lithium aluminium hydride and Grignard reagents to afford protected atrolactaldehyde and related compounds in high yield.
The invention relates to chiral compounds, methods of their preparation, and to their use in optical, electrooptical, electronic, semiconducting or luminescent components or devices, and in decorative, security, cosmetic or diagnostic applications.
