title: Lipase-catalyzed domino kinetic resolution of alpha-hydroxynitrones/intramolecular 1,3-dipolar cycloaddition: a concise asymmetric total synthesis of (-)-rosmarinecine.
abstract: The title domino reactions were developed to directly provide tetrahydrofuro[3,4-c]isoxazole derivatives (5 and 9) in > or =90% ee from racemic alpha-hydroxynitrones (2 and 6), which were used in the concise asymmetric total synthesis of (-)-rosmarinecine .
