  Unusual reversal of regioselectivity in antibody-mediated aldol additions with unsymmetrical methyl ketones

  摘要：

  A catalytic regio- and enantioselective aldol reaction of various unsymmetrical methyl ketones with para-nitrobenzaldehyde has been developed using aldolase antibodies as the catalysts. It has been found that the sense and level of regioselectivity for the reactions catalysed by antibody 38C2 and 33F12 are highly dependent on the structure of both the donor and the acceptor but in contrast, antibodies 84G3 and 93F3 catalyse the exclusive formation of the linear regioisomer independent of the structure of the reactants examined. The level of enantiocontrol is very high for most reactions. Both linear aldol enantiomers could be accessed through aldol or retro-aldol reactions using the same antibody. Theoretical studies on regioisomeric alpha- and beta-heteroatom substituted enamines derived from unsymmetrical ketones suggest that most of the linear aldol products formed in the presence of antibodies 84G3 and 93F3 must be formed from intermediate enamines which are not the thermodynamically most favourable.

  In this Letter, we studied the asymmetric direct aldol reaction of long-chain aliphatic ketones with aromatic aldehydes, using chiral diamine–polyoxometalate acid combined organocatalysts. High yields (up to 90%) and enantioselectivities (up to 90% ee) were obtained under solvent-free conditions with the optimized catalyst. Furthermore, such organocatalysts could be easily recycled and reused for four
