SYNTHESIS OF LUMINOPHORIC DERIVATIVES OF PBD BASED ON 2,5-DIARYL SUBSTITUTED THIAZOLES AND OXAZOLES

Lhotak, Pavel,Kurfuerst, Antonin

, p. 2720 - 2728 (2007/10/02)

The Friedel-Crafts acylation of 2-(biphenyl-4-yl)-5-phenyl-1,3,4-oxadiazole (PBD) with hippuryl chloride has been used to prepare the derivative V which on cyclization with POCl3 or P4S10 gives the respective oxazole (or thiazole) derivative of PBD, XIa or XIb.The reaction of carboxylic acid II with 4-(ω-aminoacetyl)biphenyl in the presence of CDI gives N-acyl-α-aminoketone VII; the analogous compound VI has been prepared by acylating ω-aminoacetophenone with acyl chloride III.The cyclization of these compounds gives bifluorophores Xa - Xd.
