A series of secondary and tertiary aryl sulfonamides were synthesized under flow conditions and evaluated for their ability to selectively inhibit tumor-associated carbonic anhydrase isoforms IX and XII. The tested compounds revealed to be highly potent CA IX inhibitors in nanomolar range, and to inhibit CA XII activity with different ranks of potencies. Remarkably, 4-methyl-N-phenyl-benzenesulfonamide

A ‘catch-and-release’ assessment of immobilised triphenylphosphine (PS-PPh3) and 1-hydroxybenzotriazole (PS-HOBt) as facilitators of acylation-mediated amide couplings is described. Through evaluations of reaction temperatures, substrate stoichiometries, solvents, and flow rates, we report findings in favour of PS-HOBt over PS-PPh3.

The abietane diterpenes—abietadiene, levopimaradiene, palustradiene, and neoabietadiene (1b–4b)—were prepared from the corresponding resin acids by diazomethane esterifications, LiAlH4 reductions, tosylations, and Zn/NaI reductions. Abietadiene was also obtained less efficiently by catechol borane reduction of abietadienal tosylhydrazone and Li/NH3 reduction of its 18-phenylthio derivative. These conjugated
通过重氮甲烷酯化,LiAlH 4还原,甲苯磺酰化和Zn / NaI还原,由相应的树脂酸制备了Abettane二萜-abietadiene,levopimaradiene,palustradiene和neoabietadiene(1b - 4b)。还可以通过邻苯二酚对甲苯磺酰hydr的邻苯二酚硼烷还原和其18-苯硫基衍生物的Li / NH 3还原而不太有效地获得己二烯。这些共轭二烯的特征在于色谱特性(HPLC,TLC,GC),MS碎裂模式,旋光度以及UV,IR,1 H NMR和13 C NMR数据。1 H和13的分配C NMR光谱由COSY,DEPT,HMQC,HMBC,NOE数据,H–H耦合分析以及与文献数据的比较得出。四个二萜被鉴定为重组松果油二烯合酶的环化产物,支持了它们在针叶树油树脂中松果油树脂酸的生物合成中的可能作用。

dangerous pests. It is a challenge to identify alternatives to the ordinary insecticides with new mode of action to be used for mosquitoes’ control in an environmentally sustainable manner. Using a facile two-step procedure, three novel series of sulfonamide-incorporating quaternary ammonium iodides (3a-i, 4a-i and 5a-i) were synthesized and their chemical structures were successfully characterized. The
