Abstract
This review represents the methods developed for the synthesis of benzimidazoles, quinoxalines and benzo(1,5)diazepines from the condensation of o-phenylenediamines with a variety of electrophilic reagents. Abstract Published data over the last years on the methods of synthesis and biological applications of azolylthiazoles are reviewed here for the first time till 2011. The review was classified according to the type of azole ring linked to thiazole. Abstract A new 1,3-benzoxazine nuclei-based fluorescent system is presented. The photophysical aspects are briefly discussed. The results suggested that the presence of oxazinic methylenes is necessary for fluorescence to be present. Abstract An efficient and mild procedure for the decarboxylative cyanomethyl esterification of arylmalonic acids has been developed. The reaction can be performed at room temperature by using chloroacetonitrile and 1,8-diazabicyclo(5.4.0)undec-7-ene (DBU) in toluene, and the desired arylacetic acid cyanomethyl esters are obtained in high yields within a short period of time.
