Total Synthesis of the Boron-Containing Ion Carrier Antibiotic Macrodiolide Tartrolon B
Mulzer, Johann,Berger, Markus
, p. 891 - 898 (2007/10/03)
The first total synthesis of the boron-containing macrodiolide antibiotic tartrolon B is reported in full detail. Two convergent approaches to the target compound are described, the first of which eventually failed, due to sensitive functionality. In the
