Unexpected Z-stereoselectivity in the Ramberg-Baecklund reaction of diarylsulfones leading to cis-stilbenes: The effect of aryl substituants and application in the synthesis of the integrastatin nucleus

Foot, Jonathan S.,Giblin, Gerard M.P.,Whitwood,Taylor

, p. 756 - 763 (2007/10/03)

With certain substituent patterns, benzyl benzyl sulfone systems have been found to give unexpectedly high Z-stereoselectivity (up to E : Z = 1 : 16) in the Meyers variant of the Ramberg-Baecklund reaction. A range of sulfones, bearing various aryl substi
