first total synthesis of vineomycin B<sub>2</sub> (<b>1</b>)
has been accomplished. The aglycon segment, a vineomycinone B<sub>2</sub> derivative, and the glycon segment, an α-l-acurosyl-l-rhodinose derivative, were prepared via C-glycosylation
using an unprotected sugar and powerful chemoselective O-glycosylation
using a 2,3-unsaturated sugar, respectively, as the key steps. Furthermore,
effective and simultaneous introduction of the two glycon moieties
to the aglycon part by concentration-controlled glycosylation led
to the total synthesis of <b>1</b>
