[source] Double Ring-Closing Metathesis Reaction of Nitrogen-Containing Tetraenes: Efficient Construction of Bicyclic Alkaloid Skeletons and Synthetic Application to Four Stereoisomers of Lupinine and Their DerivativesCHEMISTRY - A EUROPEAN JOURNAL, Issue 13 2004Shengming Ma Prof. Abstract The double ring-closing metathesis reaction of nitrogen-containing tetraenes was studied. The selectivity of the fused/dumbbell-type products can be controlled by the electronic/steric effects of the substituents attached to the CC bonds and the s - cis/s - trans conformational ratios of the substrates. This methodology has also been successfully applied to the enantioselective synthesis of four stereoisomers of lupinine and their derivatives.

A method to activate such catalysts for ring-closing reactions is presented.
