- Design, synthesis and antitumor activity of 4-aminoquinazoline derivatives targeting VEGFR-2 tyrosine kinase
-
We report herein the design and synthesis of novel 4-aminoquinazoline derivatives based on the inhibitors of VEGFR-2 tyrosine kinases. The VEGFR-2 inhibitory activities of these newly synthesized compounds were also evaluated and compared with that of ZD6

- Novel and efficient synthesis of 4-substituted-1,2,4-triazolidine-3,5- diones from anilines
-
A simple and efficient three-step synthetic procedure for the preparation of 4-substituted phenyl derivatives of 1,2,4-triazolidindiones (urazoles), starting from anilines, has been developed. In this method, aniline derivatives were reacted with 4-nitrophenyl chloroformate to provide corresponding carbamate derivatives. In the second step, semicarbazide derivatives were prepared from these carbamates by reaction with ethyl carbazate. The cyclization reaction of corresponding semicarbazides furnished 1,2,4-triazolidindiones in high yields. Copyright Taylor & Francis Group, LLC.
