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].
新化合物trans-和/或cis-spiro[5-异丙基双环[3.1.0]己烷-2,2'-环氧烷],制备新化合物的过程包括将3-异丙基-2-环戊烯-1-酮与亚磺酸甲基化物反应以形成新化合物;制备新化合物的过程包括将5-异丙基双环[3.1.0]己烷-2-酮与磺酸甲基化物或亚磺酸甲基化物反应以形成新化合物;以及制备新化合物的过程包括将3-异丙基-2-环戊烯-1-酮与亚磺酸甲基化物反应以形成5-异丙基双环[3.1.0]己烷-2-酮,然后将5-异丙基双环[3.1.0]己烷-2-酮与磺酸甲基化物或亚磺酸甲基化物反应以形成新化合物。可以从新化合物trans-和/或cis-spiro[5-异丙基双环[3.1.0]己烷-2,2'-环氧烷]中轻松制备trans-和/或cis-沙比烷水合物。
