D-(+)-Xylose has been converted into C-ring modifiedanalogues of (+)-sesbanimide A, via tricyclic aldehyde 4 as a central intermediate. The synthetic strategy involved the condensation of 4 with appropriate allylstannanes, as C-ring precursors, employing TiCl3(OiPr) as a highly effective electrophilic catalyst.
