A practical synthesis of N-tosylimines of arylaldehydes

Synthesis of N-tosylimines of arylaldehydes was carried out by the reaction of arylaldehydes and p-toluenesulfonamide in methylene chloride in the presence of trifluoroacetic anhydride as a dehydrating agent.

Synthesis of 4-arylidenecyclohexane-1,3-diones from the Baylis-Hillman acetates

Abstract Synthesis of 4-arylidenecyclohexane-1,3-dione derivatives was carried out from the Baylis–Hillman acetates. The potential utility of the prepared compounds for the synthesis of cyclohexanedione oxime ether herbicides was examined.
