, p. 764 - 768 (2007/10/02)
The behaviour of 4-benzylidene-2-oxazolin-5-one (2) and of 4-phenylazo-2-oxazolin-5-one (3) toward a variety of active methylene reagents is reported.Cleavage of the oxazolin-5-one ring was observed in most cases.A variety of new, otherwise, difficult accessible, azolyl derivatives could be prepared. - Keywords: Heterocyclic Synthesis, Pyrrolones
SYNTHESIS OF AZOLOYL KETONE AND AZOLOYLACETIC ACID DERIVATIVES: REACTIONS OF 4-ARYLAZO-2-OXAZOLIN-5-ONES WITH ACTIVE METHYLENE COMPOUNDS
Khalifa, Mohamed Ali Elsayed,Tammam, Gamal H.,Abdel-Motaleb, Ramadan M.,Elnagdi, Mohamed H.
, p. 45 - 49 (2007/10/02)
The rearrangement of 4-arylazo-2-oxazolin-5-ones (1) with active methylene compounds was investigated.The 1,2,4-triazolyl derivatives (11) could be obtained on treatment of 1 with 2-pyrazolin-5-one derivatives.The behaviour of the synthesized derivatives
