Abstract
The structures of the
dimers of N-substituted pyruvamides
are confirmed to be the pyrrolidinones (6).
4-Chloro-4-methyl-2-phenyl-2-oxazolin-5-one reacts with a-toluenethiol
to give a thiol ester which can be converted into
2-benzamido-2-benzyl-thiopropanoic acid. Reaction of the chlorooxazolinone
with thioacetic acid gives 4-acetylthio-4-methyl-2-phenyl-2-oxazolin-one
which is converted into 2-benzamido-2-mercaptopropanoic acid. The mercapto acid
is oxidized by iron(111) chloride-ether to a mixture of disulphides.
