Direct closure of a 36-membered ring using the McMurry coupling: Synthetic studies on the macrocyclic archaebacterial membrane lipids
摘要:
The synthesis of a desmethylated archaebacterial membrane lipid featuring the 36-membered ring using the McMurry coupling, a low-valent titanium induced coupling reaction of a dialdehyde, is reported.
Archaeal 72-membered macrocyclic tetraether model compounds (5 and 6) were synthesized by intramolecular dicarbonyl coupling with the aid of low-valent titanium, which is known as McMurry coupling. This synthetic methodology is the first practical way to obtain the two regioisomeric structures in quantity and appears to be applicable to the natural 72-membered tetraether lipids (3 and 4).
