A straightforward and practical synthesis of N′,N′- disubstituted N-aryl-1,2-ethylenediamines, starting from anilines, via N-aryloxazolidin-2-ones is described. A decarboxylative ring-opening reaction of N-aryloxazolidin-2-ones, using aliphatic secondary
ANOMALOUS RING OPENING OF N-ARYL-2-OXAZOLIDINONES BY ANHYDROUS ALKOXIDE:A CONVENIENT PREPARATION OF N-(ALKOXYETHYL)-2,6-DISUBSTITUTED ANILINES

N-(2-Alkoxyethyl)anilines may be prepared by acylation of an N-unsubstituted aniline with 2-chloroethyl chloroformate, ring closure to oxazolidinone, ring opening with alkoxide under anhydrous conditions to a carbamic acid salt, and decarboxylation.This unexpected mode of ring opening is especially useful in the preparation of N-(2-alkoxyethyl)-2,6-disubstituted anilines.

The 1H and 13C resonances of 3-aryl-2-oxazolidinones and 3-aryl-2-thiazolidinethiones have been examined.The conformational isomers of restricted rotation about the aryl C-N bond could not be detected for both of the nuclei.The additive shift parameters, measured for carbon chemical shifts, are found to be higher in the sulphur substituted hetero ring.
