Mehta, Goverdhan and Singh, Robindro S and Priyakumar, Deva U and Sastry, Narahari G (2003) The tricyclo[22.214.171.124 2,5]pentan-3-one system: a new probe for the study of pi-facial selectivity in nucleophilic additions. In: Tetrahedron Letters, 44 (15). pp. 3101-3104.
Monosubstituted tricyclo[2.1.0.02,5]pentan-3-one derivatives have been synthesised and subjected to hydride reduction. Quite unexpectedly and in contrast to earlier observations in related systems, anti-selectivity has been encountered in these substrates. Computational studies employing various models reproduce the observed facial preference and indicate that the causative factor for the anti-preference could be the polarization of the C1---C5 strained sigma bond.
