Abstract

Molecular mechanics calculations for the 1-substituted bicyclo[3.3.1]nonan-2-ones 2a-d show that the amount of the chair-boat conformation increases as the size of the substituent at C1 increases. This result sharply fits with the stereochemical course of NaBH4 reductions of ketones 2a-d if axial attack on the chair-boat conformation and equatorial attack on the chair-chair one are assumed to be preferential.
