Attempts to prepare the benzazepine ring system of the Rhoedine alkaloids using a Pummerer cyclization of the β-amino sulfoxide (16) gave instead the unexpected alcohol (19). The β-amino sulfoxide (16) was prepared via a diastereoselectivereduction of the β-sulfinyl enamine (8) with sodium borohydride.
Manipulatively simple and rapid methods are described for the synthesis of: chiral sulfinate esters from sulfonyl chlorides and sufonic acids; aldehydes and ketones from oximes, alcohols, hydrozones; sulfoxides from sulfides; and disulfides from thiols. The chemical yields are good to excellent and diastereoselectivity is high.
