Base Catalysed Rearrangements Involving Ylide Intermediates. Part 10. The Effects of Torsional Strain in the Transition State upon and Rearrangements
Ollis, W. David,Sutherland, Ian O.,Thebtaranonth, Yodhathai
, p. 1963 - 1968 (2007/10/02)
The and sigmatropic rearrangements of the bicyclic ammonium ylides (8), (11), and (14) are inhibited by the bicyclic framework which prevents correct orbital alignment for ?-bonding in the transition state for a concerted sigmatropic rea
