G. Mehta et al., PI-FACIAL DIASTEREOSELECTION IN REDUCTIONS OF STERICALLY UNBIASED KETONES CONTAINING THE NORBORNYL FRAMEWORK - FURTHER TESTS FOR THEORETICAL-MODELS, Perkin transactions. 2, (11), 1994, pp. 2275-2277
Ketones 3a-c exhibit syn-face selectivity in borohydride reduction; MN
DO and ah initio calculations on model and realistic transition states
, respectively, reproduce the preference, but differ on the role of el
ectrostatic and orbital effects.
