The C16 - C36 unit of halichondrin B was stereoselectively synthesized via the aldol condensation of two C16 - C26 esters with the previously synthesized C27 - C36 aldehyde followed by E ring construction. The C16 - C26 esters were prepared starting from (2S)-3-hydroxy-2-methylpropionic acid and L-tartaric acid via construction of the D ring by iodoetherification.
