  Derivatization efforts were continued to discover backups for a potent selective PPARγ modulator, DS-6930. In this Letter, the replacement of 2-pyridine ring in DS-6930 with 3- or 4-pyridyl group is reported. As the introduction of substituents on the pyridine ring did not provide potent partial agonists, modifications of benzimidazole ring were explored to discover potent intermediate agonists. 4′-Alkoxy

  继续进行衍生化工作，以发现有效的选择性PPARγ调节剂DS-6930的后备材料。在这封信中，报道了DS-6930中的2-吡啶环被3-或4-吡啶基取代。由于在吡啶环上引入取代基不提供有效的部分激动剂，因此对苯并咪唑环的修饰进行了探索以发现有效的中间激动剂。4'-烷氧基取代的苯并咪唑在体内没有显示出有效的功效，而7'-氟苯并咪唑3g（DS19161384）被发现可导致血浆葡萄糖大量降低，并具有出色的DMPK谱。

  Irradiation in the presence of N-protected amino acids at 300 nm (Rayonet) affords fluorinated arylesters by oxygenation of the 6-position in good to excellent yields and perfect regioselectivity. Even with the most suitable method investigated (ωB97XD/TApr-cc-pVDZ), deviations of up to 5 ppm from the experimental values were observed, underlining the importance of experimental measurements.
