Diastereoselectivity in Organic Reactions,l, Anh–Felkin modification of Cram’s model, Houk’s transition structure model, Houk’s electrostatic model, Cieplak’s σ → σ*# model, and cation coordination model. The intricacies, variations, and predicted selectivities of these models are elaborated with examples. It has been argued that the Ciepla

Steric and Stereoelectronic Control of Organic Molecular Structures and Organic Reactions,plication of anomeric effect in 1,4-elimination reactions, including the preservation of the geometry of the newly created double bond, is elaborated. Finally, a brief discussion on the conformational profile of thioacetals and azaacetals is presented.
