-Acyl carbazoles can be efficiently produced through a single-step process using amides and cyclic diaryliodonium triflates. This convenient reaction is facilitated by copper iodide in -xylene, using the commonly found activating ligand diglyme. We have tested this method with a wide range of amides and iodonium triflates, proving its versatility with numerous substrates. Beyond carbazoles, we also produced a variety of other -heterocycles, such as acridines, phenoxazines, or phenazines, showcasing the robustness of our technique. In a broader sense, this new method creates two C-N bonds simultaneously based on a mono-halogenated starting material, thus allowing heterocycle formation with diminished halogen waste

Degradable -Vinyl Copolymers through Radical Ring-Opening Polymerization of Cyclic Thionocarbamates.
ACS Macro Lett

School of Chemistry and Biochemistry, Georgia Institute of Technology, Atlanta, Georgia 30332, United States.
Article Synopsis
- A new method using thiocarbonyl radicals was developed to create degradable copolymers by polymerizing cyclic thionocarbamates with vinyl monomers.
- The structure of these cyclic thionocarbamates was confirmed through techniques like X-ray crystallography and NMR spectroscopy.
- The resulting copolymers display variable incorporation of thiocarbamates into the polymer backbone and can degrade under mild conditions, showing limited interaction with certain vinyl monomers.

An example of palladium/norbornene-catalyzed C-H/N-H cycloaddition of carbazoles with 2-bromobenzoic acids is presented, in which a collection of important carbazoles is expeditiously obtained. Derivatives, including acyl halides, α-oxocarboxylic acids, anhydrides, and even amides, are all allowed. Preliminary mechanistic studies reveal that a rare six-membered spiropalladacycle is involved.

N-acyl hydrazone (NAH) is recognized as a promising framework in drug design due to its versatility, straightforward synthesis, and attractive range of biological activities, including antimicrobial, antitumoral, analgesic, and anti-inflammatory properties. In the global context of increasing resistance of pathogenic bacteria to antibiotics, NAHs represent potential solutions for developing improved treatment alternatives. Therefore, this research introduces six novel derivatives of ()-N'-benzylidene-2-(6-chloro-9-carbazol-2-yl)propanehydrazide, synthesized using a microwave-assisted method.

Herein, a straightforward Bro̷nsted acids-promoted domino pathway to build substituted benzo[]carbazoles has been described from easily accessible -formyl (or -acyl) cinnamate esters and indoles. Noticeably, the protocol was amenable to protecting group-free indoles. Notably, this methodology is based on a single-pot regioselective construction of two new C-C bonds and aromatization sequences under mild and metal-free reaction conditions.
