Abstract An iodine‐PPh 3 mediated sulfenylation of indoles in water with stable and odorless sodium sulfinates as the sulfur source is described. The reaction could afford monosulfenylated moderate to excellent yields under metal free conditions. Moreover, double C—H at 2‐ 3‐positions has also been achieved by using excess optimized
Through the anchoring of copper by terminal hydroxyl groups on CeO x surface, single-atom Cu catalysts (Cu 1 /CeO ) have been synthesized and shown excellent catalytic performance in S -arylation reaction to produce diaryl disulfides.
A copper-catalyzed three-component reaction of ynones, aryl iodides, and elemental sulfur via a syn-addition process is established. The features operational practicality, broad substrate scope, readily accessible scale-up synthesis by affording series (Z)-1,2-bis(arylthio)alkenes in good to excellent yield. Moreover, benzo[b][1,4]dithiines can be also constructed efficiently using 1,2-diiodobenzene as the coupling partner.
A convenient acid-mediated reaction of β-keto sulfones with sulfoxides under metal-free conditions has been developed, thereby delivering the acid-controlled synthesis β-sulfenyl ketones and α,β-disulfonyl in good to excellent yields. The mechanism transformations studied carefully, which suggested involvement a radical process formation ketones.
Polysubstituted 3-sulfonyl naphthalenes were constructed in good to high yields by AlCl3-mediated tandem reaction of 1,4-diyn-3-yl esters and sodium sulfinates. This proceeded under mild conditions tolerated a variety functional groups. Moreover, the mechanistic studies indicated that initial formation allene DBU from ester sequence nucleophilic addition sulfinate, allene, intramolecular cyclization might be involved.
Base-controlled copper-catalyzed three-component and four-component cascade reactions of cyanamides, dirayliodonium triflates, propargylamine were established for the rapid synthesis 2-aminoimidazoles 2-iminoimidazoles.
An unprecedented copper and in situ-generated triflic acid relay-promoted four-component cascade reaction of cyanamides, diaryliodonium triflates, propargylic amines, H2O was established for rapid concise construction diverse five-membered cycloguanidines. Copper-catalyzed guanidination/intramolecular hydroamination HOTf-accelerated hydration proceeded sequentially with high level chemoselectivity regioselectivity, six new bonds were simultaneously built yields. Thus, triflates served not...
An efficient and direct nucleophilic difluoromethylation using (difluoromethyl)trimethylsilane in the presence of a Lewis base is disclosed. Several carbonyl compounds as well sulfinyl imines are successfully converted into corresponding difluoromethylated derivatives.
<div>Twelve 1,5-disubtituted and fourteen 5-substituted 1,2,3-triazole derivatives bearing diaryl or dialkyl phosphines at the 5-position were synthesised used as ligands for palladium-catalysed Suzuki-Miyaura cross-coupling reactions. Bulky substrates tested, lead-like product formation was demonstrated. The online tool SambVca 2.0 to assess steric parameters of preliminary buried volume determination using XRD obtained data in a small number cases proved be informative. Two modelling...
