Abstract

-5910",[@ IzE6-9350",[@] 278-9700"(c 0.270, dioxane). Thus the specimen of hydrindanone produced from the octalin contained 92 9 and 8 of its enantiomer which, in turn, represented the composition of the octalones 4b and 4a, respectively. The enantiomeric ratios of various octalone specimens thus were calculated from their ORD curves using the established value,[@ I222+ 11, 150", for the pure enantiomer 4b. The asymmetric induction observed ...
