Rh‐Catalyzed Cyclization of Diynes and Enynes Initiated by Carbonyl‐Directed Activation of Aromatic and Vinylic C—H Bonds.

Abstract

H Bonds. -The reaction of diynes with aryl ketones or enones gives 1,3-dienes bearing pyrrolidine, cyclopentane or cyclohexane rings. The enantioselective reaction of enynes affords the products with high e.e. -(TSUCHIKAMA, K.; KUWATA, Y.; TAHARA, Y.-K.; YOSHINAMI, Y.; SHIBATA*, T.; Org. Lett. 9 (2007) 16, 3097-3099; Dep. Chem.
