The diastereoselectivities exhibited by sterically unbiased -tricyclo(5.2.1.02,6)decan-10-ones in nucleophilicadditions can be modulated through substituents in the distal five membered ring.
π-Facial selectivities in nucleophilic additions to 4-hetero-tricyclo[5.2.1.02,6]decan-10-ones and 4-hetero-tricyclo[5.2.1.02,6]dec-8-en-10-ones: an experimental and computational study
Several endo-tricyclo[5.2.1.02,6]decan-10-ones and endo-tricyclo[5.2.1.02,6]dec-8-en-10-ones with hetero atom modifications at the distal C-4 position have been subjected to hydridereduction. π-Face selectivities in these systems are largely governed by the same electronic factors that were earlier identified in the case of the norbornyl system. A computational study demonstrates good predictability
