The effect of temperature, catalyst and pressure on the outcome of the Diels-Alder reaction of 5(S)-E-5,6-O-isopropyliden-hex-3-en-2-one with cyclopentadiene was investigated. All four possible Diels-Alder adducts were isolated and characterized on the basis of single crystal X-ray analysis and NMR
Treatment of an aldehyde and a 1,3-diene with N-sulfinyl-p-toluenesulfonamide/boron trifluoride etherate leads to products of an imino Diels-Alder reaction via an N-sulfonyl imine produced in situ.
