摘要
The right mix! When one considers the many ways in which a polyfunctional organometallic species may be quenched before any productive C-C bond formation can occur (two amide protons, five esters), the samarium-promoted coupling between sulfide 1 and aldehyde 2 is remarkably efficient (see scheme). This is shown in the synthesis of a stable mimic of the sialylTn (Tn = GalNAcα1 → O-Ser/Thr) disaccharide.
