Cyclohexenone synthesis
WebThe cyclohexenone core of welwitindolinones was synthesized by a Rh (I)-catalyzed [5 + 1]-cycloaddition of an allenylcyclopropane with CO. A pentasubstituted cyclopropane was prepared successfully by a Rh (II)-catalyzed intramolecular cyclopropanation of alkenes with chlorodiazoacetates. Supporting Information WebSynthesis. There are several different synthetic routes for the production of cyclohexenone. The reduction and acid hydrolysis of 3-ethoxy-2-cyclohexen-1-one is available for the laboratory scale. The precursor is accessible from resorcinol via 1,3-cyclohexanedione.
