The stereoselective and convergent synthesis of the C12–C28 segment 2 of the apoptosis inducing macrolide antibiotic, apoptolidin (1), is described. The synthesis involves a highly stereoselective tin(II)-mediated aldol reaction between the C17–C22 ethyl ketone 3 and the C23–C28 aldehyde 4 as the key step.
