- 中文摘要: The asymmetric induction in the complexation reaction of (S)-1-methyl-2-(5-methyl-cyclohexa-1,4-dienylmethyloxy)- pyrrolidine 5 and (S)-2-(2-N,N-dimethylamino-1-propanoxy)-5- methylcyclohexa-1,4-diene 6 having heteroatom adjacent the stereogenic center has been investigated. The diastereoselectivity was determined directly from the diastereotopic peaks in the /sup 1/H NMR or by chemical correlation with 9. The conversion of .eta.-1,4-complexes 7a and 8a to 9 proceeded with high retention of configuration while that of the .eta.-2,5-Fe(CO)/sub 3/ complexes 7b and 8b undergoes considerable racemization.
