✦ Synopsis

Phenyliodine(III) Bis(trifluoroacetate) Mediated Synthesis of Phenanthro[9, Fused Isoxazoles and Pyrimidines.

-Different oxidizing agents for the non-phenolic coupling of the 4,5-diarylheterocycles (I) and (III) are examined. The hypervalent iodine reagent PIFA in the presence of BF 3 •OEt 2 is found to be an efficient combination to prepare the synthetically useful fused target compounds in high yields. -(OLIVERA,
