The synthesis of O-substituted and O-unsubstituted 3-hydroxy-4-thioxo-oxazolidin-2-ones,
functionalised 4-imino-oxazolidine-2-ones and 4-phenoxy-imino-oxazolidin-2-one starting
from O-substituted and O-unsubstituted 3-hydroxy-4-imino-oxazolidin-2-ones is described.
A one-pot protocol for the preparation of 4-methoxyimino-, 4-aralkoxyimino- and 4-phenoxyimino-oxazolidin-2-ones
has been developed.
heterocycles - oxazolidin-2-ones - Dimroth rearrangement - thionation - ring closure
