چکیده

The relative energies of the chair and boat transition states of a variety of Ireland-Claisen rearrangements were obtained by B3LYP/6-31G calculations. Theoretical results are in good agreement with experimental data and provide a quantitative analysis of the origins of boat preferences that are observed in some of these reactions.

Stereo- and regioselective organic transformations based on main group organometallic reagents- application to the stereocontrolled Claisen rearrangements

Unprecedented stereocontrolled Claisen rearrangement of allylic vinyl ethers has been developed with modified organoaluminum reagents A and B as an example of diastereoselective activation of ethereal substrates. The stereoselective activation of ether moiety is the subject of our current interest. Oxygenophilic organoaluminum reagents are known to exhibit the great tendency to form stable ethe...

Stereoselective Synthesis of Quaternary Carbons via the Dianionic Ireland–Claisen Rearrangement

A dianionic Ireland-Claisen rearrangement of chiral, nonracemic α-methyl-β-hydroxy allylic esters has been developed that proceeds with high diastereoselectivity and provides products containing three contiguous stereogenic carbons, including a quaternary center. The potential utility of the rearrangement for complex molecule synthesis is also demonstrated.
