The C3-C17 segment of a boron containing ionophoric antibiotic aplasmomycin (1), the key intermediate in Corey's total synthesis of 1, was stereoselectively synthesized in an optically active form. This synthesis involved stereoselective construction of the two segments, (+)-dithiane 3 (C3-C11) and (+)-aldehyde 4 (C12-C17), based on remote controlled asymmetric reductions of the corresponding ketones
含有硼的离子载体抗生素阿霉素(1)的C3-C17片段是Corey总合成1的关键中间体,以光学活性形式立体选择性地合成。该合成涉及将相应的酮远程控制地不对称还原为关键步骤,并连接两个部分,分别立体构筑两个部分(+)-二硫杂环己烷3(C3-C11)和(+)-醛4(C12-C17)。3和4通过反式双键形成(+)-二硫杂环丁2(C3-C17),这是Corey 1合成中的关键中间体。
