Abstract
A three-component reaction between 5,5-dimethylcyclohexan-1,3-dione (dimedone), aromatic aldehydes, and acetonitrile in the presence of chlorosulfonic acid afforded N-[(2-hydroxy-4,4-dimethyl-6-oxocyclohexene-1-yl)-aryl-methyl]-acetamides in good yields. The temperature-dependent 1H NMR of one of the products has been investigated.
