A simple catalytic, redox-neutral access to 3-methylcyclohexenones has been developed via rhodium catalysis in the presence of an amine additive and Ag2CO3. This process utilized simple aldehydes and acetone as substrates and tolerates a variety of functional groups. Disubstituted phenols were isolated in moderate yields when Cu(OAc)2 was employed as an oxidant.

A facile and convenient method for the synthesis of cyclohexenone compounds was developed using an l-proline immobilized silica gel catalyst combined with a continuous-flow approach. Because of the mild reaction conditions, ease of catalyst recyclability, and product isolation, this reaction approach can potentially be used in a facile scale-up reaction or in industrial applications. the Partner Organisations 2014.
Organocatalyst-mediated aldolrobinson cascade reactions: A convenient synthesis of substituted cyclohex-2-enones

A convenient organocatalytic process for the chemoselective synthesis of substituted cyclohex-2-enones was developed. The cascade reaction involves a remarkable Michael addition of an acyclic ketone-based enamine onto unmodified enones. The enamine-mediated aldolRobinson cascade reactions of aromatic and aliphatic aldehydes with acetone produced substituted cyclohex-2-enones in moderate to high yields under mild reaction conditions.

Reductive cyclization of 2,6-dimethyl-3,5-dicarboxyethyl-4-aryl-1,4- dihydropyridines using sodium and methanol as solvent produces the 5-aryl-3- methyl-2-cyclohexen-1-ones.
