Abstract

2-[β-(Phenylamino)vinyl]-5-(1,1-dimethyl-2-acetoxyethyl)-4(5H)-oxazolonium perchlorate was synthesized. The deprotonation ability of this compound in chloroform by the action of sodium carbonate to give 4(5H)-oxazolone, containing enamine fragment at C(2) in the ring was studied. Z,E-Isomerization at the double bond was found at room temperature by the action of the solvents.
