Abstract

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 <i>V</i> which on cyclization with POCl<sub>3</sub> or P<sub>4</sub>S<sub>10</sub> gives the respective oxazole (or thiazole) derivative of PBD, <i>XIa</i> or <i>XIb</i>. The reaction of carboxylic acid <i>II</i> with 4-(<i>o</i>-aminoacetyl)biphenyl in the presence of CDI gives <i>N</i>-acyl-α-aminoketone <i>VII</i>; the analogous compound <i>VI</i> has been prepared by acylating of <i>o</i>-aminoacetophenone with acyl chloride <i>III</i>. The cyclization of these compounds gives bifluorophores <i>Xa - Xd</i>.
