Iodocyclization Reactions for the Desymmetrization of Cyclohexa-1,4-dienes
摘要:
Fifteen examples are presented showing that various modes of cyclization (5-endo, 5-exo, 6-endo, 6-exo, and 7-endo) can be used for the desymmetrization of cyclohexa-1,4-dienes. All take place with complete diastereocontrol and good yield.

The Prinscyclisation has been used for the first time to desymmetrise a 1,4-diene. Products derived from both normal Prins and rearrangement pathways were obtained, all with complete stereocontrol.
