摘要:Abstract Isothiocyanates (ICTs) are a group of molecules that can be used for many different purposes, they exhibit anticancer, antimicrobial, antibiotic, and anti-inflammatory properties. The synthesis of isothiocyanates has been a focus of many researchers for nearly the p...

摘要:Abstract N -Heterocyclic carbenes and their metal complexes have found applications in many organic transformations. Apart from the privileged C 2-symmetry present in modern enantioselective catalysis, ligands bearing C 1-symmetry have witnessed growing atte...

摘要:Abstract The reactivity of N -thiophthalimides with silyl chalcogenides is described. Treatment of N -thiophthalimides with bis(trimethylsilyl) sulfide [(Me3Si)2S] leads to the formation of a mixture of the corresponding disulfides and trisulfides. On the ot...

摘要:Abstract Regio- and stereoselective ring-opening reaction of 2-bromomethyl-1,3-thiaselenole with thiols proceeded as nucleophilic attack at the selenium atom of seleniranium intermediate affording unsaturated selanyl sulfides, ( Z )-CH2

摘要:Abstract The S -benzyl thioester and methyl ester derivatives of a representative 4-pyridinone-based carboxylic acid were sufficiently activated to react efficiently in amide coupling reactions with the amide anion generated in situ from the N -trimethylsilyl derivative of differ...

摘要:Abstract We describe the use of allylic rearrangements of cyanophosphates for the efficient and practical synthesis of 3-(tetrazol-5-yl)-3,5-pregnadien-20-one, which is a potent 5α-reductase inhibitor (IC50: 15.6 nM), from pregnene-3,20-dione in 92% overall yield ...

摘要:Abstract A novel decarboxylative N -arylation of indole-2-carboxylic acids with aryl halides is developed. The reaction proceeds efficiently in the presence of Cu2O as the catalyst to give the corresponding N -aryl indoles in high yields. This synthetic method shows go...

摘要:Abstract This review covers the methods that chemists have developed to access halogenated polycyclic structures from polyenes, by emulating Nature’s enzymatic machineries. From pioneering studies to the most recent developments, the different strategies, whether based on th...

摘要:Abstract An efficient method for the C-4-selective addition of quinoline derivatives to carbonyl compounds is described. The combination of 2-ethoxy-1-ethoxycarbonyl-1,2-dihydroquinolines (EEDQs) with a palladium catalyst and diethylzinc generates nucleophilic allyl species which...

摘要:Abstract Sulfocoumarins are key structural motifs in several bioactive molecules. Herein, we describe a simple, one-pot procedure for the synthesis of structurally diverse sulfonocoumarin-3-carboxylates by heating 2-hydroxyaryl aldehydes with an active sulfonyl chloride in t...
