β-(1-Hydroxybut-3-enyl)indoles, which are prepared in high yields from indole-3-carbonyl compounds, could be converted into 1-(β-indolyl)1,3-butadienes, yuehchukene and derivatives, and murrapanine in one step under various acid-catalyzed reaction conditions in THF. As the reactions of β-(1-hydroxypropenyl)indole1 3with alcohol4and8agave exclusively bisnoryuehchukene7cand trinoryuehchukene7d, respectively, our present work also gives strong evidence to support the asssumption that reactions of this type indeed proceed from a Diels-Alder pathway.
