Rhodium‐Catalyzed Asymmetric [2+2+2] Cycloaddition Reactions of 1,6‐Enynes and Oxabenzonorbornadienes

Rhodium‐Catalyzed Asymmetric [2+2+2] Cycloaddition Reactions of 1,6‐Enynes and Oxabenzonorbornadienes

The asymmetric [2+2+2] cycloaddition reactions of 1,6‐enynes and oxabenzonorbornadienes was accomplished by using the complex of [Rh(COD)2]BF4 and (R)‐Xyl‐P‐Phos as chiral catalyst. A range of 1,6‐enynes and oxabenzonorbornadienes were well tolerated in the cycloaddition reaction, which afforded var...

Zusammenfassung:The asymmetric [2+2+2] cycloaddition reactions of 1,6‐enynes and oxabenzonorbornadienes was accomplished by using the complex of [Rh(COD)2]BF4 and (R)‐Xyl‐P‐Phos as chiral catalyst. A range of 1,6‐enynes and oxabenzonorbornadienes were well tolerated in the cycloaddition reaction, which afforded various polycyclic products with asymmetric quaternary carbon centers generally in excellent enantioselectivities.
