Arylsulfenium Ion Promoted Cascade Cyclizations of Deactivated Aryldienes. An Investigation into Reagent-Based Acceleration of Cationic Annulation
摘要:
The efficiency of sulfenylative cyclization has been shown to be strongly influenced by both substrate substitution pattern and the structure of the external sulfenium ion source. Of the various reagents examined, 8-methoxethyl 4-chlorobenzenesulfenate (9b) has been found a particularly effective initiator for the regioselective cyclization of a range of aryldienes at low temperature.
