  Studies Toward the Synthesis of Luminacin D:  Assembly of Simplified Analogues Devoid of the Epoxide Displaying Antiangiogenic Activity

  摘要：

  [GRAPHICS]A series of structurally simplified luminacin analogues devoid of the epoxide ring are assembled in a stereocontrolled manner from 2,4-dimethoxybenzaldehyde using a syn-selective aldol reaction as the key step. The success of the approach is critically dependent on the nature and extent of the alcohol protecting groups. The synthetic analogues inhibit VEGF-stimulated angiogenesis in an in vitro assay indicating that the epoxide is not essential for biological activity in this compound class.
