An Improved Total Synthesis of 5'-Deoxytoyocamycin

In this paper, we report an efficient total synthesis of 5-deoxytoyocamycin, which was isolated from microbial sources with excellent antitumor activity. Our synthetic strategy uses 1,2,3-triacetate-5-deoxyribose as the starting material and Vorbrüggen glycosylation as the key step.
