  2-(Trifluoroacetyl)-1,3-azoles reacted with 3-aminopyrazoles to give the corresponding trifluoromethyl-substituted alcohols. The conditions required for the reaction and the yields of the products were highly dependent on the electronic nature of the both the 1,3-azole and the 3-aminopyrazole units.

  2-(三氟乙酰基)-1,3-唑与3-氨基吡唑反应，生成相应的三氟甲基取代醇。反应所需的条件和产物的收率在很大程度上取决于1,3-唑和3-氨基吡唑单元的电子性质。

• Discovery of Novel Pyrazolo-pyridone DCN1 Inhibitors Controlling Cullin Neddylation

  Chemical control of cullin neddylation is attracting increased attention based largely on the successes of the NEDD8-activating enzyme (E1) inhibitor pevonedistat. Recently reported chemical probes enable selective and time-dependent inhibition of downstream members of the neddylation trienzymatic cascade including the co-E3, DCN1. In this work, we report the optimization of a novel class of small molecule inhibitors of the DCN1-UBE2M interaction. Rational X-ray co-structure enabled optimization afforded a 2S-fold improvement in potency relative to the initial screening hit. The potency gains are largely attributed to additional hydrophobic interactions mimicking the N-terminal acetyl group that drives binding of UBE2M to DCN1. The compounds inhibit the protein-protein interaction, block NEDD8 transfer in biochemical assays, engage DCN1 in cells, and selectively reduce the steady-state neddylation of Cul1 and Cul3 in two squamous carcinoma cell lines harboring DCN1 amplification.
