  Relative Stereochemical Determination and Synthesis of the C1−C17 Fragment of a New Natural Polyketide

  摘要：

  The challenging determination of the relative stereochemistry of a complex natural polyketide portion was achieved. After careful NMR analysis, a concise synthesis of a set of possible relative diastereomers (only 6 diastereomers out of the 32 initially envisioned) has been carried out using a common strategy based on enantioselective aldol reactions. With a high predictability, final NMR comparison established the relative stereochemistry of the C1-C17 fragment of this natural product.
