High throughput synthesis of 2,5-substituted indoles using a titanium carbenoid bearing boronate functionality [PDF]

open access: yes, 2008
A titanium benzylidene complex bearing a boronate group converted resin-bound esters into enol ethers. Suzuki cross-coupling with aryl iodides followed by cleavage with acid completed the solid-phase synthesis of 2,5-disubstituted N-Boc-indoles.

Ni-Catalyzed Aryl Sulfide Synthesis through an Aryl Exchange Reaction.

open access: yesJournal of the American Chemical Society, 2021
A Ni-catalyzed aryl sulfide synthesis through an aryl exchange reaction between aryl sulfides and a variety of aryl electrophiles was developed. By using 2-pyridyl sulfide as a sulfide donor, this reaction achieved the synthesis of aryl sulfides without ...

Direct acylation of aryl amines using dimethylformamide and dimethylacetamide as the acyl resources

open access: yesJournal of Saudi Chemical Society, 2016
The treatment of aryl amines with dimethylformamide (DMF) and dimethylacetamide (DMA) in the presence of hydrochloric acid brings about efficient N-acylation to give the corresponding aryl formamides and aryl acetamides in acceptable to excellent yields.

Manganese carbonyl-mediated reactions of azabutadienes with phenylacetylene, methyl acrylate and other unsaturated molecules [PDF]

open access: yes, 2004
Reaction of PhCH₂Mn(CO)₅ with l,4-di-aryl-1-aza-1,3-butadienes gave substituted pyrrolinonyl rings which were η⁴-coordinated to a Mn(CO)₃ group. These are formed by intramolecular CO insertion into a (non-isolated) cyclomanganated intermediate, followed ...

Synthesis of Morphinans through Anodic Aryl‐Aryl Coupling

open access: yesThe Chemical Record, 2021
AbstractThe morphinans are an important class of structurally fascinating and physiologically important natural products as exemplified by the famous opium alkaloids of the morphine family. Although this class of secondary metabolites from the juice of the opium poppy capsule was already used for medicinal purposes thousands of years ago, chemical ...
