| titleOfInvention | Chiral catalysts for asymmetric acylation and related transformations |
| abstract | A chiral catalyst comprising a 3, 4-disubstituted pyridine, or a salt, N functionalised derivative, dimer or oligomer thereof, wherein the 3-substituent is substantially hindered from rotation about the bond (sp<SUP>2</SUP>-sp<SUP>2 </SUP>biaryl axis) linking it to pyridine and the 4-substituent is an aliphatic or aromatic amine linked by a single bond to the pyridine, the pyridine nitrogen being functionalised or unfunctionalised, preferably comprising a compound of formula I wherein Z is a group substantially hindered from rotation about its bond; and each of R<SUP>1 </SUP>and R<SUP>2 </SUP>are independently selected from C<SUB>1-30 </SUB>alkyl, C<SUB>3-30 </SUB>cyclo alkyl and/or C<SUB>3-30 </SUB>aryl, or NR<SUP>1 </SUP>R<SUP>2 </SUP>form a cyclic amine; wherein R<SUP>1 </SUP>and/or R<SUP>2 </SUP>may be optionally substituted and/or include one or more heteroatoms; a composition or support comprising the catalyst; process for the preparation and resolution thereof; process for stereoselective reaction of an optically inactive substrate using the catalyst; and the optically active reaction product thereof. |
