Cross-trienamines in asymmetric organocatalysis. [PDF]
J Am Chem Soc, 2012 Cross-conjugated trienamines are introduced as a new concept in asymmetric organocatalysis. These intermediates are applied in highly enantioselective Diels-Alder and addition reactions, providing functionalized bicyclo[2.2.2]octane compounds and γ'-addition products, respectively.
