Reaction of lithioenamines with sulphinate esters. Stereospecific and stereoselective synthesis of β-enamino and β-imino sulphoxides
Abstract
Reaction of lithioenamines with (–)-menthyl (S)-toluene-p-sulphinate affords optically active β-enamino and/or β-imino sulphoxides, depending on the structure of the starting imine. The optical stability of both these classes of compounds is investigated.
