  Synthesis of Mayolene-16 and Mayolene-18:  Larval Defensive Lipids from the European Cabbage Butterfly

  摘要：

  A tandem Wittig approach has been employed for the synthesis of both (11S,9Z,l2Z,15Z)- and (11R,9Z,12Z,15Z)-hydroxyoctadeca-9,12,15-trienoic acid (11-hydroxylinolenic acid, 11-HLA) from (R)-glyceraldehyde acetonide. From (11R)-HIA we have prepared the corresponding palmitic acid and stearic acid esters, mayolene-16 (1) and mayolene-18 (2), insect defensive compounds recently identified from Pieris rapae larvae. In addition, we describe the synthesis of three macrocyclic oligomers (24-26) derived from (11R)-HLA.

• Chiral Silylation Reagents for the Determination of Absolute Configuration by NMR Spectroscopy

  We have investigated the use of chiral silylating reagents as analytical probes for determining the absolute stereochemistry of natural products by NMR spectroscopy. These reagents are prepared in high chemical yield in one step and can be used to derivatize chiral allylic alcohols which are incompatible with ester-based methodologies. Microscale ( approximately 400 nmol) derivatization conditions

  我们已经研究了使用手性甲硅烷基化试剂作为分析探针通过NMR光谱法测定天然产物的绝对立体化学的方法。这些试剂可一步一步以高化学产率制备，可用于衍生与基于酯的方法不相容的手性烯丙基醇。已经定义了微型（约400 nmol）衍生条件。所得的硅氧烷非对映异构体容易通过它们的（1）H NMR谱来区分。
