6-Chloro-2,6,7,7-tetramethyl-2-octene (4), prepared via prenyl chloride addition to 2,3,3-trimethyl-1-butene, at room temperature undergoes a zinc chloride/hydrogen chloride-catalysed cyclocondensation to yield 1,2,3,3,6,6-hexamethyl-1-cyclohexene (1).The reaction mechanism is elucidated by isolation of intermediate five-membered carbocycles and by force field calculations.
