stannanes 3 and 4 have been prepared by treatment of the allylic sulfones 6 and 7 with tributyltin hydride under free-radical conditions and shown to react under non-catalysed and Lewis acid promoted conditions with 4-nitrobenzaldehyde to give the anti- and syn-products 9/11 and 8/10, respectively, with reasonable levels of stereoselectivity. The 2-arylsulfinylpropenylstannanes 17 and 18 were also
