Abstract
4-Acetoxy- and 4-trifyloxy-2,6,6-trimethyl-2,4-cyclohexadienones were employed as non-dimerizing alternatives to 2,6,6-trimethyl-2,4-cyclohexadienone in Diels-Alder reactions with substituted acetylenes which facilitated the synthesis of substituted bicyclo[2.2.2]octen-2,5-diones, bicyclo[2.2.2]octadienones and 5-methylenebicyclo[2.2.2]octen-2-ones.Keywords
