2-Cyclohepten-1-one Usage And Synthesis
UsesA cycloheptenone derivative, a key intermediate for the synthesis of perhydroazulene terpenoids.
Synthesis Reference(s)The Journal of Organic Chemistry, 41, p. 2073, 1976 DOI: 10.1021/jo00873a055
General Description2-Cyclohepten-1-one is an α,β-enone and its regioselective reaction with allyl indium reagent in the presence of TMSCl has been reported. It reacts with Bu2Zn in the presence of catalytic amounts of Cu(OTf)2 and CH2-bridged azolium salts to give (S)-3-butylcycloheptanone.
