  • Polysubstituted Oxygen Heterocycles by a Reformatsky-Type Reaction/Reductive Cyclization Approach from Enantiopure β-Ketosulfoxides
    作者:Françoise Colobert、Sabine Choppin、Leticia Ferreiro-Mederos、Michel Obringer、Sandra Luengo Arratta、Antonio Urbano、M. Carmen Carreño
    DOI:10.1021/ol701670g
    日期:2007.10.1
    The stereoselective synthesis of tetrasubstituted tetrahydrofurans and trisubstituted tetrahydropyrans bearing a sulfoxide was achieved by reductive cyclization (Et3SiH/TMSOTf) from the corresponding enantiopure hydroxy ketones protected as a dioxolane. These derivatives are easily accessible from a Reformatsky-type reaction between alpha-bromo-alpha'-sulfinyl ketones and protected alpha- or beta-ketoaldehydes
    带有亚砜的四取代四氢呋喃和三取代四氢吡喃的立体选择性合成是通过还原环化反应(Et3SiH / TMSOTf),由相应的对映纯羟基酮作为二氧戊环来实现的。这些衍生物很容易从α-溴-α'-亚磺酰基酮与受保护的α-或β-酮醛之间的Reformatsky型反应,然后非对映选择性地还原所得的β-酮亚砜来获得。
  • Reformatsky-Type Reaction of Chiral Nonracemic α-Bromo-α‘-sulfinyl Ketones with Aldehydes. Synthesis of Enantiomerically Pure 2-Methyl-1,3-diol Moieties
    作者:Michel Obringer、Françoise Colobert、Benjamin Neugnot、Guy Solladié
    DOI:10.1021/ol027223+
    日期:2003.3.1
    Chiral nonracemic alpha-bromo-alpha'-sulfinyl ketones were shown to react with aldehydes in the presence of SmI(2) in a Reformatsky-type reaction to give the corresponding adduct with excellent syn diastereoselectivity. Further reduction of the Reformatsky adducts furnished anti- and syn-2-methyl-1,3-diol moieties in excellent yields and diastereoselectivities.

  • SmI2-coupling reaction of chiral non-racemic α-bromo-α′-sulfinyl ketones with imines: synthesis of enantiomerically pure 2-methyl-3-amino-1-ol moieties
    作者:Marie Barbarotto、Julie Geist、Sabine Choppin、Françoise Colobert
    DOI:10.1016/j.tetasy.2009.11.020
    日期:2009.12
    Chiral non-racemic alpha-bromo-alpha'-sulfinyl ketones were shown to react with imines in the presence of SmI2 to give the corresponding 1,3-aminoketo derivatives with good syn-diastereoselectivity. Further reduction of these adducts either with DIBAL-H only or with DIBAL-H in the presence of Yb(OTf)(3) afforded syn- and anti-2-methyl-3-amino-1-ol moieties, respectively, in good yields and diastereoselectivities.

    日期:2009.8.20
    Efficient synthesis of the fragment C9−C16 bearing the anti,syn stereotriad of ansamycin antibiotics is described. Key steps for controlling the configuration of the three stereogenic centers involve a stereoselective Reformatsky-type reaction followed by a diastereoselective reduction of a β-ketosulfoxide.

    sequence that involves a SmI2-promoted stereoselective Reformatsky addition of chiral nonracemic α-bromo α′-sulfinyl ketones to various aldehydes followed by stereoselective reduction of the Reformatsky adduct. The absolute configuration of the products was determined by comparison with literature data and by 1H NMR NOESY experiments. The observed stereoselectivities can be explained in terms of a boat
