  Synthesis of a C20−C26 Segment of Superstolide A by Addition of a Chiral Allenylzinc Reagent to (R)-N-Boc Alaninal

  摘要：

  Additions of chiral allenylzinc and indium reagents to N-Boc alaninal were examined as a possible route to a C20-C26 segment of superstolide A. Allenylzinc reagents, prepared in situ by palladiozincation of (R)- and (S)-5-pivalyloxy-3-butyn-2-ol mesylate, showed excellent reagent control to afford the anti,syn and anti,anti diastereomers as the nearly exclusive adducts.

  Studies towards the synthesis of superstolide A. Synthesis and stereochemical assignment of the C(21)C(26) fragment of superstolide A

  摘要：

  An asymmetric synthesis of the C(21) C(26) fragment of superstolide A is described. A fragment, corresponding to a reductive ozonolysis product of superstolide, as also prepared. Comparison of spectroscopic and optical properties of the corresponding fragment obtained by degraduation of natural superstolide A allowed the confirmation of the stereochemistry of the natural product.
