The addition of chiral N-acyloxazolidinone enolates to diene-molybdenum and dienyl-iron complexes gives enantiomeric excesses as high as 80percent.The oxazolidinone derived from valinol adds preferentially to the pro-S terminus of the diene/dienyl complex while the oxazolidinone derived from norephedrine adds to the pro-R terminus.A rationalization of these experimental results is attempted based on Seebach's topological rules for the Michael addition of enamines to nitro olefins.
