  Coupling of Propylene Oxide and Lactide at a Porphyrin Chromium(III) Center

  摘要：

  5,10,15,20-Tetraphenylporphyrin chromium chloride (TPPCrCl) with added [Ph3P-N-PPh3]Cl+ (PPN+Cl) selectively polymerizes lactide (l and rac) dissolved in neat propylene oxide (PO) to yield polylactide (PLA) terminated by the -OCHMeCH2Cl group. At 0 degrees C and below, rac-LA yields polymers highly enriched in isotactic tetrads (iii). At 25 degrees C, some stereoselectivity is lost as transesterification becomes significant, and at 60 degrees C and above, enchainment of PO leads to the formation of 3,6-dimethyl-1,4-dioxan-2-one by a backbiting mechanism. At 0 degrees C, after the enchainment of l-(S,S)-LA in neat (R)-(+)-PO, the formation of (3S,6R)-3,6-dimethyl-1,4-dioxan-2-one occurs, while at higher temperatures the ratio of (3S,6R)-3,6-dimethyl-1,4-dioxan-2-one to (3R,6R)-3,6-dimethyl-1,4-dioxan-2-one falls to 3:2.

• Palladium-CatalyzedO-Allylation of α-Hydroxy Carbonyl Compounds

  α-Hydroxy carbonyl compounds undergo smooth O-allylation using allylic carbonates and Pd(0) catalysts. This method has significant advantages over other O-allylation methods as it provides a solution to several problems previously observed for this synthetic transformation.

  日期：2007.3

  Four new chiral δ-substituted allylic trichloroacetimidates have been synthesised to probe the origin of the high diastereoselectivity observed for the MOM-ether directed palladium(II)-catalysed aza-Claisen rearrangement. Rearrangement of these compounds has not only provided strong evidence for this directing effect but also that during the rearrangement both oxygen atoms from the MOM-ether are involved

• The Tandem Ring‐Closing Metathesis–Isomerization Approach to 6‐Deoxyglycals

  日期：2008.7.7

  synthesized de novo as single isomers starting from ethyl lactate by using the tandem RCM-isomerization reaction as the key step. Different relative configurations become accessible by addition of vinyl- or allyl-metal compounds to protected lactaldehydes under Cram-chelate or Felkin-Anh control. The concept is exemplified for glycals of L-rhodinose and L-amicetose, as well as for ring-expanded non-natural

  通过使用串联RCM异构化反应作为关键步骤，从乳酸乙酯开始作为单一异构体从头合成了受保护的3,6-二脱氧乙二醇。通过在Cram-螯合物或Felkin-Anh控制下将乙烯基或烯丙基金属化合物添加到受保护的乳醛中，可获得不同的相对构型。该概念以L-罗丹糖和L-乙酰糖的糖基以及其环扩展的非天然类似物为例。这种新的缩醛方法也适用于通过重复策略合成二糖缩醛，例如L-若丹糖及其非天然扩环类似物的二聚体。
• 1,4-Dioxamacrolides: Preparation and Sensory Properties
  作者：Marcus Eh

  DOI：10.1055/s-2003-37345

  The synthesis of 3-methyl-1,4-dioxacylopentadecan-2-one (12c) and 3-methyl-1,4-dioxacylohexadecan-2-one (12d), two new musk odorants, is described starting from methyl 2-bromopropionic acid (6b) and allylic alcohol, respectively. The key step of the synthesis is the ring-closing olefin metathesis (RCM) to the unsaturated 1,4-dioxamacrolides. Insight into the structure-odor relationship (SOR) is provided by the synthesis of ten related unsubstituted or methyl substituted oxamacrolides. Finally, a four step enantioselective synthesis of both (3R)-(+)- and (3S)-(-)-3-methyl-1,4-dioxacyclopentadecan-2-one as well as (3R)-(+)- and (3S)-(-)-3-methyl-1,4-dioxacyclohexadecan-2-one reveals that mainly the (3R)-(+) enantiomers are responsible for the powerful musky odor characteristic. Their synthesis starts from ethyl (2S)-2-hydroxy­propanoate (14) or isobutyl (2R)-2-hydroxypropanoate (15) which were treated under acidic conditions with allyl trichloroacetimidate (16), followed by titanate mediated transesterification, ring-closing olefin metathesis and hydrogenation.

  本文介绍了分别从 2-溴丙酸甲酯（6b）和烯丙基醇开始，合成 3-甲基-1,4-二氧杂环戊烷-2-酮（12c）和 3-甲基-1,4-二氧杂环十六烷-2-酮（12d）这两种新型麝香气味剂。合成的关键步骤是通过闭环烯烃偏析（RCM）生成不饱和的 1,4-二氧杂环戊烷。 通过合成十种相关的未取代或甲基取代的氧杂二茂酰胺，深入了解了结构-气味关系（SOR）。最后，对 (3R)-(+)- 和 (3S)-(-)-3- 甲基-1,4-二氧杂环十五烷-2-酮以及 (3R)-(+)- 和 (3S)-(-)-3- 甲基-1,4-二氧杂环十六烷-2-酮进行了四步对映体选择性合成，结果表明主要是 (3R)-(+) 对映异构体产生了强烈的麝香气味特征。 它们的合成始于(2S)-2-羟基丙酸乙酯(14)或(2R)-2-羟基丙酸异丁酯(15)，在酸性条件下用三氯乙酰亚氨烯丙基酯(16)处理，然后进行钛酸酯介导的酯交换反应、闭环烯烃偏聚反应和氢化反应。
