ASYMMETRIC SYNTHESIS OF ( plus )-2,2,3-TRIMETHYLHEX-4-ENAL VIA NUCLEOPHILIC ATTACK ON eta 3-1,3-DIMETHYLALLYL COMPLEXES OF MOLYBDENUM.

Nucleophilic attack on mixtures of endo and exo isomers of molybdenum complexes provide facile routes to optically pure allylically substituted olefins. A given configuration at the metal center controls the configuration at the allylic center because the exo isomer is attacked preferentially and attack occurs cis to the nitrosyl. Full-matrix least-squares refinement using anisotropic thermal parameters for the molybdenum and isotropic thermal parameters for the remaining non-hydrogen atoms converged to the final residuals R//1 equals 0. 069 and R//2 equals 0. 066.
