Discodermolide: very complex chainlike compound (13 stereocenters)
Representative example of current methods for control of acyclic chemistry.
- Key enantioselective reaction
Allylic boronate, allenyl stannanes, oxazolidinone auxiliaries,
boron enolate, and allylic silane
- Key coupling strategy
Suzuki-Miyaura, Negishi, NHK, and Wittig
High degree of convergency, robustness, and scaled-up synthesis!!
