This invention relates to a new class of compounds of the indole series. Particularly, it relates to novel thio esters of 1-(p-chlorobenzoyl)-5-methoxy-2-methylindole-3-acetic acid. These novel compounds are prepared by reacting 1-(p-chlorobenzoyl)-5-methoxy-2-methylindole-3-acetic acid with an appropriate thiol and diethyl phosphorocyanidate or diphenyl phosphorazidate in the presence of triethylamine in a dimethylformamide solution. These compounds are useful anti-inflammatory agents.
hCE1, a phenyl ester type that is more easily metabolized by hCE1 than by hCE2, and a carbonate ester type that is easily metabolized by both hCE1 and hCE2. The hydrolyticrate of 1-methylpentyl (hexan–2–yl) ester was 10–times lower than that of 4–methylpentyl ester in hCE1 solution. hCE2 was susceptible to electron density of the substrate, and there was a difference in the hydrolysis rate of up to 3
Stille reaction is designed for the first time, allowing for the construction of a rich range of C(sp3)−C(sp3), C(sp3)−C(sp2), and C(sp3)−C(sp) bonds in good to high yields with excellent stereoselectivity under exceptionally mild conditions. The innovative use of synergistic photoredox/nickel catalysis enables a novel single-electron transmetalation process of stannane reagents, providing a new research

cSrc kinase inhibition assays were evaluated at a 10 μM concentration. The selected candidates displayed limited activities against the various tested kinases; the compounds 2a, 3b, 6a, 7a, 7b and 8a showed no activity to weak activity (% inhibition = ∼0-10%). The molecular docking study revealed the importance of the thioester moiety for the interaction of the drugs with the amino acids in the active

cross-coupling reactions of thioesters by selective acyl C(O)–S cleavage have emerged as a powerful platform for the preparation of complex molecules. Herein, we report divergent Liebeskind–Srogl cross-coupling of thioesters by Pd–NHC (NHC = N-heterocycliccarbene) catalysis. The reaction provides straightforward access to functionalized ketones by highly selective C(acyl)–S cleavage under mild conditions. Most
