  Synthesis of enantioenriched .alpha.-hydroxy-.alpha.-allenylacetic acids by [2,3] Wittig rearrangement of .alpha.-(propargyloxy)acetates

  摘要：

  Optically active (R)-(propargyloxy)acetic esters 5, available in ca. 90% ee through reduction of alkynones 2 with Chirald-LiAlH4 followed by alkylation with chloroacetic acid and esterification with CH2N2, undergo highly stereoselective [2,3] rearrangement upon treatment with LDA in THF at -78-degrees-C followed by Cp2ZrCl2 to afford alpha-(S)-hydroxy-beta-(R)-allenic esters 7 with complete transfer of chirality and > 90% diastereoselectivity. Upon treatment with TESOTf in Et3N the (R)-(propargyloxy) acetic esters 5 afford the diastereomeric alpha-(R)-hydroxy-beta-(R)-allenic esters 8 stereoselectively. Both hydroxy esters 7 and 8 cyclize stereospecifically to trans- and cis-2,5-dihydrofurans 13-15 and 17-19 upon treatment with AgNO3-CaCO3, PhSeCl, or NBS.

  A fine addition! A highly enantioselective and efficient procedure for the amino‐alcohol–zinc‐catalyzed addition of trimethylsilylacetylene to aromatic, α,β‐unsaturated, and aliphatic aldehydes has been developed (see scheme; R=aryl, alkynyl, or alkyl; TMS=trimethylsilyl; TBDMS=tert‐butyldimethylsilyl). The present protocol was successfully applied in the concise synthesis of the natural products marine

  很好的补充！已开发出一种高度对映选择性和高效的程序，用于氨基醇锌催化的三甲基甲硅烷基乙炔加成到芳族，α，β-不饱和和脂肪族醛中（见方案； R =芳基，炔基或烷基； TMS =三甲基甲硅烷基； TBDMS =叔丁基二甲基甲硅烷基）。本协议已成功地应用于天然产物海洋炔醇和法卡林二醇的简明合成中。

  Allenylstannanes (S)-4 and (R)-4, available in ca. 90% ee from alkynones 1 through reduction with the LiAlH4-Darvon alcohol or -ent-Darvon alcohol complex, followed by S(N)2' displacement on the derived mesylates (R)-3 or (S)-3 with Bu3SnLi.CuBr.Me2S, readily add to various aldehydes under Lewis acid catalysis to afford optically active homopropargylic alcohols with good to excellent syn diastereoselectivity. With 2-(benzyloxy)propanal (48), MgBr2-catalyzed reactions are highly stereoselective, affording the syn adduct 49 from the (S)-stannane (S)-4 and the anti adduct 52 from the (R)-stannane (R)-4. BF3-promoted additions give mainly or exclusively the syn adducts 49 and 51. Additions of (S)- and (R)-4 to (R)-3-(benzyloxy)-2-methylpropanal (61) yield the syn adducts 62 and 64 as major or exclusive products.

  The BF3-promoted addition of (S)-allenylstannane (S)-6 to aldehyde 16 afforded a 68:32 mixture of diastereomeric homopropargylic alcohols 17 and 18 whereas MgBr2-promoted addition gave adduct 17 as the exclusive product. The (R)-allenylstannane (R)-6, on the other hand, yielded a 30:1 mixture of syn and anti alcohol adducts 19 and 20 with BF3.OEt2 and a 1:92 mixture favoring the anti adduct 20 under MgBr2 catalysis.
