Synthesis of 2??Cycloalkenones (Parts of 1, 4??Diacyl??1, 3??butadiene Systems) and of a Heterocyclic Analogue by Metal??Catalyzed Decomposition of 2?? …
Abstract Furans with side-chains at C (2) of various lengths terminating in diazomethyl keto groups are shown to undergo Rh 2 (OAc) 4-catalyzed furan unravelling with the production of 2-cyclopentenone, 2-cyclohexenone, and 2-cycloheptenone to each of whose olefinic C (β) is attached an acrylaldehyde unit. Interposition of a cyclohexane or a methylaminomethylene moiety between the furan and diazoketo functions leads to the ...
