Cyclohexadienones, substituted, preparation reactions

Cyclohexadienones, substituted, preparation of, 46,119 reactions of, 46,119 Cyclohexane from reduction of chloro-cyclohexane, 47,105 A -o-Cyclohexaneacetic acid, ethyl ESTER, 45, 44... [Pg.125]

The alkylation procedure can be used to prepare a wide variety of 2-substituted-2,4-cyclohexadienones, 2,3 5i 6 which are useful starting materials. The compounds can serve either as dienes or dienophiles7 in the Diels-Alder reaction and can be opened photochemically to yield substituted A3,5-hexadienoic acids.8... [Pg.119]

The phenol-dienones could be conveniently prepared directly from phenols by reaction with Br2 in the presence of AgC104 and Na2C03. These dienones are transformed efficiently to the 4-alkoxycyclohexa-2,5-dienones by the silver ion mediated reaction in the presence of the corresponding alcohols (equation 96) 48s solid-phase bromina-tion of ferf-butyl-substituted phenols with N-bromosuccinimide also affords halogenated cyclohexadienones . ... [Pg.654]

Cycloaddition. The reagent has been used in Diels-Alder reactions to prepare 4-acyl-4-substituted cyclohexadienones after selenoxide elimination. Examples ... [Pg.204]
