SYNTHESIS AND STRUCTURE OF STERICALLY CROWDED POLYNUCLEAR ARYL DERIVATIVES OF FIVE-MEMBERED N-HETEROCYCLES, ORTHO ANALOGS OF POPOP
Three sterically crowded polynuclear aryl derivatives of five-membered N-heterocycles, viz. ortho analogs of 1,4-bis(5-phenyloxazol-2-yl)benzene (POPOP), were synthesized and their structure studied by x-ray structure analysis and IR and Raman spectroscop

Aromatic Carbonylation Regio-Controlled by Oxazole and Isoxazole Rings, Novel Route to Heterocycle-Substituted o-Benzoates
3,5-Diphenylisoxazole and 2,5-diphenyloxazole were regioselectively carbonylated under an atmosphere of carbon monoxide after the formation of arylpalladium(II) intermediates, to give bioactive o-benzoates substituted by isoxazole and oxazole rings in goo
