  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.

  From sugar to cycloadduct: The effect of the trans‐acetonide blocking group and the stereochemistry of the substituents on the regio‐ and stereoselectivity in the intramolecular nitrone–alkene cycloaddition (INAC) reaction of hept‐6‐enoses (see scheme) is reported and studied by using theoretical analysis.
