  • A Practical Chiral Bicyclic Thioglycolate Lactam Auxiliary for Stereoselective Quaternary Carbon Formation
    作者:Azélie Arpin、Jeffrey M. Manthorpe、James L. Gleason
    DOI:10.1021/ol060106k
    日期:2006.3.1
    [reaction: see text] Chiral bicyclic thioglycolate lactams may be prepared in three steps from inexpensive commercial materials. The resulting lactams may be alkylated three times, twice using basic enolization and once using reductive enolization, to form alpha-quaternary carboxylic acid derivatives in high yield and with high diastereoselectivity. The alkylation products may be cleaved under either
    [反应:见正文]手性双环硫代乙醇酸酯内酰胺可以由廉价的商业原料分三步制备。可以将所得内酰胺进行三次烷基化,使用碱性烯醇化两次,使用还原烯醇化一次,以高收率和高非对映选择性形成α-季羧酸衍生物。可以在酸性或还原性条件下裂解烷基化产物以分别提供羧酸或伯醇。
  • Stereoselective construction of a quaternary carbon substituted with multifunctional groups: application to the concise synthesis of (+)-ethosuximide
    作者:Tomoaki Abe、Tatsuo Suzuki、Kazuhiko Sekiguchi、Seijiro Hosokawa、Susumu Kobayashi
    DOI:10.1016/j.tetlet.2003.10.081
    日期:2003.12
    Synthetically useful β,γ-unsaturated carbonyl compounds having a quaternary carbon at the α-position were prepared with high stereoselectivity by the reaction of a dienolate anion derived from α,β-unsaturated imide having a chiral auxiliary and electrophiles (ethyl acetate and allyl iodide as the C2 and C3 unit, respectively). This method was applied to a short asymmetric synthesis of (+)-ethosuximide
