in highly functional molecules. We now report that a solid fluorosulfuryl imidazolium triflate salt delivers the same “F−SO2+” fragment to Nu−H acceptor groups in the substrates. However, this triflate salt is a far more reactive fluorosulfurylating agent than SO2F2 and displays selectivity preferences of its own. Moreover, the new azolium triflate reagent reacts once with primary amines and anilines
已经发现,硫酰氟SO 2 F 2在各种环境中,甚至在高功能分子中,都可以使苯酚衍生化。现在,我们报告固体三氟甲磺酸氟磺酰基咪唑鎓盐向底物中的Nu-H受体基团传递相同的“ F-SO 2 + ”片段。但是,这种三氟甲磺酸盐是一种比SO 2 F 2更具活性的氟磺化剂,并显示出其自身的选择性偏好。而且,在停止反应之前,新的三氟甲磺酸偶氮鎓试剂与伯胺和苯胺反应一次。另一方面,用三乙胺和两当量的“ F-SO 2 +“供体存在,它以良好的收率继续进行双(氟硫磺酰基)酰亚胺的转化-这是我们从未见过的两个重要的转化反应,我们将磺酰氟用作亲电试剂。

molecularly complex (hetero)aryl carboxylicacids into the bioisostere world: A functional-group-tolerant and operationally simple decarbonylative alkynylation is reported that allows the synthesis of aryl alkynes from highly functionalized aryl and heteroaryl carboxylicacids. The reaction shows an unmatched substrate scope mainly thanks to its remarkably mild reaction conditions using a homogenous Pd/Cu

reactions. However, in the case of CuAAC reactions, the availability of azide reagents is limited owing to their potential toxicity and the risk of explosion involved in their preparation. Here we report another reaction to add to the clickreaction family: the formation of azides from primary amines, one of the most abundant functional groups5. The reaction uses just one equivalent of a simple diazotizing

The disclosure provides at least one entity chosen from compounds of Formula I, a tautomer thereof, a deuterated derivative of that compound or tautomer, and a pharmaceutically acceptable salt of any of the foregoing, compositions comprising the same, and methods of using the same, including uses in treating APOL1-mediated diseases, including pancreatic cancer, focal segmental glomerulosclerosis (FSGS), and/or non-diabetic kidney disease (NDKD).
reaction was applied to the highly efficient synthesis of new N,N′-disubstituted sulfamide (R1NH–SO2–NHR2) derivatives as pesticide candidates. Bioassays were conducted to evaluate both insecticidal and fungicidal activities of the target compounds. Preliminary results showed that the target molecules exhibited good bioactivities. In particular, insecticidal activities of compounds D25 and D21 against Plutella
