The construction of the fragments C1-C9 3 and C17-C27, 4a of the bryostatins in a enantioselective and highly diastereoselective fashion is described. The usefulness of the "chiron" approach is illustrated with the synthesis of these fragments from, respectively, D-pantolactone (6) and D-isobutyl lactate (23) as chiral templates.
构建了布雷抑酶素(bryostatins)的片段C1-C9 3和C17-C27 4a,采用了对映选择性和高非对映选择性的方式。通过分别以D-泛醇内酯(6)和D-异丁基乳酸酯(23)为手性模板合成这些片段,说明了“四手型”方法的实用性。
