DIELS-ALDER REACTIONS OF 2-ACETYL-2-CYCLOHEXENEONE WITH ENOL ETHERS AND EMAMINES
Snider, Barry B.
, p. 1133 - 1136 (1980)
2-Acetyl-2-cyclohexenone (2) undergoes inverse electron demand Diels-Alder reactions with enol ethers at 25 deg C.The adduct in which the oxygen adds ando is favored.Trans substituted enol ethers are cc. 35 times as reactive as the cis isomer.Enamines react immediately with 2 at 25 deg C.
