  trans-Acetonide Controlled endo-Selective Intramolecular Nitrone−Alkene Cycloaddition of Hept-6-enoses:  A Facile Entry to Calystegines, Tropanes, and Hydroxylated Aminocycloheptanes

  摘要：

  High-yielding endo-selective intramolecular nitrone-alkene cycloaddition (INAC) reactions of hept-6-enoses controlled by a trans-acetonide to give bridged bicyclo[4.2.1]isoxazolidines exclusively are realized for the first time. The cycloadducts were readily transformed into calystegine, tropane, and hydroxylated aminocycloheptane frameworks.

• Aqueous reactions with a Lewis acid and an organometallic reagent. The scandium trifluoromethanesulfonate-catalyzed allylation reaction of carbonyl compounds with tetraallyltin
  作者：Iwao Hachiya、Shu Kobayashi

  DOI：10.1021/jo00077a009

  日期：1993.12

  The allylation reaction of a wide variety of carbonyl compounds with tetraallyltin was successfully carried out in aqueous media by using scandium trifluoromethanesulfonate (scandium triflate) as a catalyst.
• Chelation control associated with organometallic addition reactions in water. The high stereoselectivity offered by α- and β-hydroxyl substituents obviates the need for protecting groups

  DOI：10.1016/00404-0399(50)1439o-

  日期：1995.9.18

  High stereoselectivities have been observed for indium-promoted allylations of alpha- and beta-hydroxy aldehydes in aqueous media, with strong implication that chelate control can continue to operate in water.
