Synthesis of Functionalized 3,4-Dihydro-2H-pyrans by Hetero - Diels-Alder Reaction of an Enaminoketone with Enol Ethers
The hetero - Diels-Alder reaction of 3-(N-acetylbenzylamino)-2-cyano-1-phenyl-2-propen-1-one (3) with enol ethers (4) leads to diastereomeric cycloadducts 5 and 6 in good yields.The structure of the products is discussed in terms of configuration and pref
