The effect of ligands on the endo-exo selectivity of Lewis-acid catalysed Diels-Alder reactions has received little attention. Interestingly, Yamamoto et al." reported an aluminium catalyst that produces mainly exo Diels-Alder adduct. The endo-approach of the diene, which is normally preferred, is blocked by a bulky group in the ligand.  [c.91]

However, fiirtlier analysis of the linear regression expression in A3.8.1 is required to achieve a iisefid expression for the rate constant both from a computational and a conceptual points of view. Such an expression was first provided by Yamamoto [6], but others have extended, validated, and expounded upon his analysis in considerable detail [7, 8]. The work of Chandler [7] in this regard is followed most closely here in order to demonstrate the places in which condensed phase effects can appear in the theory, and hence in the value of the themial rate constant. The key mathematical step is to differentiate both sides of the linear regression fomuila in (A3.8.1) and tlien carefiilly analyse its expected behaviour for systems having a barrier height of at least several times T. The resulting expression for the classical forward rate constant in temis of the so-called reactive flux time correlation fiinction is given by [6, 7 and 8]  [c.885]

Similar reasoning shows that were one to view along tiieX, Yand Z axes and polarization analyse the signal each time, whether excited by linearly or by naturally polarized light, the total intensity should be given by + 2/.

The regioselectivity benefits from the increased polarisation of the alkene moiety, reflected in the increased difference in the orbital coefficients on carbon 1 and 2. The increase in endo-exo selectivity is a result of an increased secondary orbital interaction that can be attributed to the increased orbital coefficient on the carbonyl carbon ". Also increased dipolar interactions, as a result of an increased polarisation, will contribute. Interestingly, Yamamoto has demonstrated that by usirg a very bulky catalyst the endo-pathway can be blocked and an excess of exo product can be obtained The increased di as tereo facial selectivity has been attributed to a more compact transition state for the catalysed reaction as a result of more efficient primary and secondary orbital interactions as well as conformational changes in the complexed dienophile" . Calculations show that, with the polarisation of the dienophile, the extent of asynchronicity in the activated complex increases . Some authors even report a zwitteriorric character of the activated complex of the Lewis-acid catalysed reaction " . Currently, Lewis-acid catalysis of Diels-Alder reactions is everyday practice in synthetic organic chemistry.  [c.12]
