title: Synthesis of taurospongin A.
abstract: Two new routes to the C(1-10) carboxylic acid core of taurospongin A are presented. In the first route, overall asymmetric hydration of a C(2)-C(3) alkene is achieved by Sharpless AD and selective deoxygenation at C(2); in the second route, the C(3) stereogenic center is set by Tietze asymmetric allylation. A short synthesis of the C(1'-25') fatty acid combines with the product from the first route to complete the total synthesis of taurospongin A.
