, p. 5083 - 5102 (2007/10/03)

The synthesis of Segment B corresponding to the C26-C17 portion of tautomycin was accomplished by coupling reaction between the epoxide (Sub-segment B-l) and the dithiane (Subsegment B-2). The degradation product of tautomycin corresponding to the C26-C19 portion was also synthesized from Sub-segment B-1.
