experimental part, p. 284 - 293 (2012/06/16)
Chiral phosphorus-olefins (S)-1, (S)-4, and (S)-5 have been designed and synthesized. These ligands were all synthesized from (S)-phenylalanine derivatives and act as phosphorus-olefin bidentate ligands to rhodium. The coordination face of the olefin can

supporting information; experimental part, p. 6123 - 6125 (2011/07/30)
Novel chiral phosphorus-olefin bidentate ligands have been synthesized in a few steps from a readily available enantiopure compound. These ligands have been applied to a rhodium-catalyzed asymmetric addition of organoboroxines to N-sulfonyl aldimines, achieving high yield and enantioselectivity.
Ring closing metathesis of phenyl-substituted dienes
Bujard,Briot,Gouverneur,Mioskowski
, p. 8785 - 8788 (2007/10/03)
A series of phenyl-substituted heterodienes 2a-f and 6 was prepared and subjected to ring closing metathesis (RCM) to give differently phenyl- substituted dihydropyrroles and dihydrofuran.
