  An Expeditious Total Synthesis of Both Diastereoisomeric Lipid Dihydroxytetrahydrofurans from Notheia anomala

  摘要：

  Short, high yielding syntheses of both diastereomers of the naturally occurring oxylipids 1 and 2 using a combination of organocatalytic hydroxylation of an aldehyde, alkene cross metathesis, and palladium(0) catalyzed cyclization chemistry (six-step process) are reported. Furthermore, the influence of the catalyst on the cross metathesis reaction of the homoallylic 1,2-diol has been studied in detail.

• Development of a Concise and General Enantioselective Approach to 2,5-Disubstituted-3-hydroxytetrahydrofurans

  Concise syntheses of 2,5-disubstituted-3-hydroxytetrahydrofurans have been developed that provide access to each configurational isomer of this scaffold from a single aldol adduct. Application of these methods to the rapid preparation of (6S,7S,9S,10S)- and (6S,7S,9R,10R)-6,9-epoxynonadec-18-ene-7,10-diol, two structurally related marine epoxylipids, is reported.

• Protecting-group-directed stereodivergent Tsuji–Trost cyclization: total synthesis of oxylipids and (+)-petromyroxol

  A stereodivergent protecting-group-directed Tsuji–Trost cyclization for efficient synthesis of both 2,5-cis- and 2,5-trans-disubstituted-THF scaffolds has been realized. The presence of a β-O-silyl group in allyl acetate results in cis-2,5-disubstituted-3-oxygenated THF in a good up to 9 : 1 dr. Alternatively, when the free OH at the β-position is available for acetate co-ordination, it gives a trans-2

  已经实现了立体发散保护基导向的 Tsuji-Trost 环化，可有效合成 2,5-顺式和 2,5-反式二取代-THF 支架。乙酸烯丙酯中β- O-甲硅烷基的存在导致顺式-2,5-二取代-3-氧化 THF 的比例高达 9:1 dr。或者，当 β 位的游离 OH 可用于乙酸酯配位时，它会产生反式-2,5-二取代-3-羟基 THF 支架，几乎是单一的非对映异构体（高达 1:0 dr）。合成的 THF 支架在氧脂和 (+)-petromyroxol 的全合成中进行。
• Inverse Temperature Dependence in the Diastereoselective Addition of Grignard Reagents to a Tetrahydrofurfural
  作者：Jeffrey Mowat、Baldip Kang、Branden Fonovic、Travis Dudding、Robert Britton

  DOI：10.1021/ol900324s

  日期：2009.5.21

  A remarkable example of inverse-temperature-dependent diastereoselectivity was uncovered while investigating the addition of Grignard reagents to a 3-hydroxytetrahydrofurfural. The free hydroxyl group in the tetrahydrofurfural was found to play a key role in these processes, a result corroborated through a series of DFT calculations that also highlighted an entropic preference for the formation of one diastereomer.
