An Approach to the Diastereoselective Synthesis of Cyclohexane-1,3-dicarboxamide Derivatives via a Pseudo Five-Component ­Reaction Based on Diketene

A one-pot pseudo five-component reaction for the synthesis of 2-aryl-4-hydroxy-4-methyl-6-oxo-N 1,N 3-dialkylcyclohexane-1,3-dicarboxamide derivatives involving different primary amines, various aromatic aldehydes, and diketene in the presence of triethylamine with high yields is achieved.
