  Thiopyran Route to Polypropionates:  An Efficient Synthesis of Serricornin

  摘要：

  The synthesis of serricornin [(4S, 6S, 7S)-7-hydroxy-4,6-dimethylnonan- 3-one], a sex pheromone produced by the female cigarette beetle (Lasioderma serricorne F.), in seven steps from readily available racemic 1,4-dioxa-8- thiaspiro-[4.5] decane-6-carboxaldehyde (6) is described. The key steps include enantioselective aldol reaction of 6 with tetrahydrothiopyran-4- one catalyzed by 5-[(2S)-pyrrolidine-2-yl]-1H- tetrazole to fabricate the tetrapropionate skeleton, stereoselective (LiBu3BH)-Bu-s reduction of the resulting aldol adduct, Barton-McCombie deoxygenation, and Raney nickel desulfurization.

  The aldol reaction of tetrahydro-4H-thiopyranone with 1,4-dioxa-8-thiaspiro[4.5]decane-6-carboxaldehyde (I) gives four possible diastereomeric adducts (II). Aldol reactions of I with each of the diastereomers of II and their corresponding methoxymethyl ethers III via the Ti enolates were investigated. Using racemic reactants, reactions with II proceeded with high levels of mutual kinetic enantioselection

  tautomerization of an acyclic derivative assembled by sequential substrate-controlled stereoselective aldol reactions of a chiral ketone with two achiral aldehydes. Although the trioxaadamantane tautomer was shown to be thermodynamically more stable than alternative forms, the kinetic barrier to cyclization was significant. This observation raises doubts about the proposed formation of muamvatin as an

• The Thiopyran Route to Polypropionates:  Enantioselective Synthesis of Membrenone B from Racemic Fragments
  作者：Vishal Jheengut、Dale E. Ward

  DOI：10.1021/jo701546f

  日期：2007.9.1

  [GRAPHICS](6S,7S,8S,9R,10S)-(-)-Membrenone B was synthesized in nine steps (9.4% overall yield) beginning with two-directional aldol coupling of tetrahydro-4H-thiopyran-4-one with racemic 1,4-dioxa-8-thiaspiro[4.5]decane-6-carboxaldehyde. The first aldol reaction occurs with dynamic kinetic resolution to give a single adduct (>98% ee). The second aldol reaction is highly diastereoselective (three of eight possible adducts), and both major products are converted to membrenone B. The route also constitutes a formal synthesis of membrenone A.

  Enantioselective protonation of the s-BuLi derived lithium enolate of (S)-phenyl 1,4-dioxa-8-thia-spiro[4.5]decane-6-carbothioate 14 with N-isopropylephedrine 15 gives 14 as a 10:1 mixture of enantiomers. Recrystallization of nonracemic 14 gives a highly enantioenriched material (>90% ee), which can be converted into 1,4-dioxa-8-thia-spiro[4.5]decane-6-carboxaldehyde 2 without racemization. Diastereoselective aldol reactions of tetrahydro-4H-thiopyran-4-one with nonracemic 2 proceed with negligible racemization to give adducts that are useful building blocks for polypropionate synthesis.
