Nucleophilic Phosphine-Catalyzed Iodocyclization of Isoprenoids Bearing an Oxygen Terminal Group
摘要:
The nucleophilic phosphine-catalyzed diastereoselective iodocyclization of linear isoprenoids bearing an oxygen terminal group was investigated. TBDMS ether of homogeraniol and TBDMS ester of homogeranic acid were successfully converted to the corresponding iodopolycyclic products in the presence of a catalytic amount of triphenylphosphine with complete diastereoselectivity.
Various C–C and C‐X bonds could be formed by doublefunctionalization of olefins featuring Cu‐mediated assistedtandemcatalysis. Furthermore, one‐pot indoline syntheses with o‐bromostyrenes as an application could be achieved.
