  Stereoselective Synthesis of the C13-C28 Subunit of (-)-Laulimalide Utilizing an α-Chlorosulfide Intermediate

  摘要：

  A stereoselective route to the C13-C28 subunit of (-)-laulimalide is described. l-Tartaric acid is the source of the hydroxy groups at C19 and C20. An -chlorosulfide is employed as the key intermediate for the creation of the C17-C18 bond and the C16-C17 double bond was introduced using the Mislow-Braverman rearrangement and Hutchin's dexoxygenation with concomitant double bond transposition reaction. The C15 and C23 stereogenic centers were created using catalytic asymmetric reactions. The trisubstituted and trans-disubstituted alkenes were created stereoselectively by taking advantage of ring-closing metathesis and the Julia-Kocienski olefination reaction, respectively.
