Palladium catalyzed amidation
WebApr 7, 2024 · In 2015, the Zou's group [17] first realized the amide C−N activation by Pd‐phosphine complex at 110 °C. Since then, many palladium‐catalyzed such reactions have been reported. For example, Szostak and co‐workers [18] reported a Pd‐catalyzed highly chemoselective cross‐coupling between geometrically activated amides and … WebAlthough the palladium-catalyzed Suzuki-Miyaura cross-coupling of aryl esters has received significant attention, there is a lack of methods that utilize cheap and readily accessible Pd-phosphane catalysts, and can be routinely carried out with high cross-coupling selectivity. ...

WebThe synthesis of 8-amido- and 8-aminopurines by a single palladium-catalyzed protocol is reported. The method proceeds efficiently and tolerates a wide range of amides and amines as coupling partners, including aryl, alkyl, sulfone, and acetal amides, as well as deactivated m- and p-nitroanilines. WebHere we report a palladium catalyzed γ-C−H arylation of amines using catalytic amounts of alkyl acetals as transient activators (e.g. commercially available (2,2-dimethoxyethoxy)benzene). This simple additive enables arylation of amines with a wide range of aryl iodides.
WebSep 22, 2024 · Our new borate-catalyzed amide coupling reaction has many advantages over existing methods for amidation: It uses a simple, commercially available catalyst, and the protocol proceeds with high efficiency (low PMI value), with a remarkably broad substrate scope, including application to the synthesis of many pharmaceutically relevant … Web摘要： "I" did it: A sequential intramolecular amination/N-demethylation/amidation of internal acetylenes in the presence of a catalytic amount of Pd(OAc)2 and nBu4NI afforded indolo[3,2-c]isoquinolinones under mild aerobic conditions (see scheme, DMSO=dimethyl sulfoxide).
