  • Novel compounds spiro[5-isopropylbicyclo[3.1.0]hexane-2,2'-oxiranes], process for the production of the novel compounds, and process for the production of sabinene hydrates therefrom
    Patent number: 4162258
    Abstract: Novel compounds trans- and/or cis-spiro[5-isopropylbicyclo[3.1.0]hexane-2,2'-oxiranes], process for the production of the novel compounds comprising reacting 3-isopropyl-2-cyclopenten-1-one with sulfoxonium methylide to form the novel compounds, process for the production of novel compounds comprising reacting 5-isopropylbicyclo[3.1.0]hexan-2-one with sulfonium methylide or sulfoxonium methylide to form the novel compounds, and process for the production of novel compounds comprising the steps of reacting 3-isopropyl-2-cyclopenten-1-one with sulfoxonium methylide to form 5-isopropylbicyclo[3.1.0]hexan-2-one and then reacting the 5-isopropylbicyclo[3.1.0]hexan-2-one with sulfonium methylide or sulfoxonium methylide to form the novel compounds. Trans- and/or cis-sabinene hydrates can readily be prepared from the novel compounds trans- and/or cis-spiro[5-isopropylbicyclo[3.1.0]hexane-2,2'-oxiranes].
