The sesquiterpenes provide a rich storehouse of diverse carbocyclic structural types whose perverse nature has taxed the talent and imagination of organic chemists since the beginning of modern organic chemistry. Studies on this widely varied group of natural products have contributed significantly to the advancement of spectroscopic techniques, mechanistic insight, and synthesis methodology, and the trend along these lines shows no sign of letup, as new and increasingly complex structures join the list of known members. Indeed, almost every conceivable carbon skeleton derivable via rational chemical transformations of farnesol (1), the biological precursor of the sesquiterpenes (80), seems to have found its way into one or another species of plant life. |
