METHODS FOR PRODUCING CHIRAL ALDEHYDES |
摘要 |
<p>The present invention relates to methods for producing chiral aldehydes by the enantioselective hydroformylation of prochiral substrates with the aid of a catalyst consisting of a transition metal and a chiral ligand, characterized in that said chiral ligand is a compound of general formula 1wherein the rings R7-R10 drawn with dotted lines are optional and one or more of rings R1-R6 or R7-R10 are substituted with one or more independently selected substituents of general formula -(CH2)x(CF2)yF(x=0-5; y=1-12) or their branched isomers. In particular, the invention relates to the conducting of the mentioned methods in compressed (liquid or supercritical) carbon dioxide as the reaction medium.</p> |
