Abstract
|
A novel and efficient procedure was introduced for the
synthesis of alkyl acetates bearing arylthio and quinoxaline
moieties from the reaction of o-phenylenediamines, dialkyl
acetylenedicarboxylates, and in-situ generated arylsulphenyl
chlorides in DMF as solvent at room temperature. The
procedure worked well for a variety of starting materials and
the corresponding products were obtained in good yields.
Moreover, some derivatives of dialkyl 2-amino-3-thiomalates
were stereoselectively synthesized via the reaction of amines,
dialkyl acetylenedicarboxylates and in-situ generated arylsulphenyl
chlorides in moderate to good yields in DCE as solvent
at room temperature.
