Organocatalytic (3+3)-cycloaddition of <i>ortho</i>-substituted phenyl nitrones with aryl cyclopropane carbaldehydes: a facile access to enantioenriched 1,2-oxazinanes
The first asymmetric (3+3)-cycloaddition of ortho-substituted phenyl nitrones with aryl cyclopropane carbaldehydes has been demonstrated by secondaryamine catalysts. While the other ortho-substituents gave 1,2-oxazinanes, ortho-hydroxy ones provided a novel class of tetrahydrochromeno-1,2-oxazine cores via rare 1,3-aryl migration, followed by cyclization. An unusual type of asymmetric approach was
