Synthesis of Yuehchukene Analogues, Murrapanine and Normurrapanine Utylizing Thermal Reaction of b-(1-Hydroxybutenyl)indoles under Neutral Reaction Conditions
摘要:
beta-(1-Hydroxybutenyl)indoles, which were prepared in high yields from indole-3-carboxaldehyde, could be converted into yuehchukene analogues(8a, b) murrapanine (9a) and normurrapanine (9b) in one step under thermal-induced reaction conditions in neutral solution of ethylene glycol and water. beta-(1-Hydroxybutenyl)indoles are supposed to be dehydrated to 1-(beta-indolyl)-1,3-butadienes which react further to yuehchukene analogues via a Diels-Alder pathway. Murrapanine and normurrapanine showed a cytotoxicity toward KB cells.
