One-pot two-step facile synthesis of 2,3,5,6-tetrafluorobenzonitrile-containing dithiocarbamic acid esters

A simple and efficient route for the construction of 2,3,5,6-tetrafluorobenzonitrile-substituted dithiocarbamic acid esters via selective C-F bond cleavage of pentafluorobenzonitrile is proposed. This procedure combines the nucleophilic addition of various nitrogen anion to CS moiety and the nucleophilic substitution of the in situ formation of thiocarboxylate anion with pentafluorobenzonitrile in one-pot and enables a rapid access to the products in moderate to excellent yields. The synthesized product is a promising intermediate for further transformation.

Hydroaminoalkylation/Buchwald-Hartwig amination sequences for the synthesis of benzo-annulated seven-membered nitrogen heterocycles

Reaction sequences consisting of an initial intermolecular titanium-catalyzed hydroaminoalkylation of a suitably ortho-bromophenyl-substituted alkene and a subsequent intramolecular Buchwald-Hartwig amination are used for the synthesis of benzazepine, benzoxazepine, and benzothiazepine derivatives. While in the latter two cases, the hydroaminoalkylation products obtained from an allyl (2-bromophenyl) ether or an allyl (2-bromophenyl) thioether must be purified prior to the subsequent palladium-catalyzed amination step, both reactions can be combined to an efficient one-pot procedure for the synthesis of 2,3,4,5-tetrahydrobenzo[b]azepines when 4-(2-bromophenyl)-1-butene and various N-methylanilines are used as the starting materials.

A tethering directing group strategy for ruthenium-catalyzed intramolecular alkene hydroarylation

We report a new catalyst design for N-heterocycle synthesis that utilizes an alkene-tethered amide moiety as a directing group for aromatic C-H activation. This tethering directing group strategy is demonstrated in a ruthenium-catalyzed intramolecular alkene hydroarylation with N-aryl acrylamides to form oxindole products.

Copper(II)-Catalyzed Selective Reductive Methylation of Amines with Formic Acid: An Option for Indirect Utilization of CO2

A copper-catalyzed protocol for reductive methylation of amines and imine with formic acid as a C1 source and phenylsilane as a reductant is reported for the first time, affording the corresponding methylamines in good to excellent yields under mild conditions. This protocol offers an alternative method for indirect utilization of CO2, as formic acid can be readily obtained from hydrogenation of CO2.

A novel cycloaddition reaction of alpha-diazo-gamma-amido ketones catalyzed by rhodium(II) acetate. Scope and mechanistic details of the process

alpha-Diazo ketones containing an amido group in the gamma-position have been found to underdo a novel rhodium(II)-catalyzed cycloaddition reaction. Intramolecular cyclization of the keto carbenoid onto the oxygen atom of the amide group generates a carbonyl ylide dipole as a transient species. This highly stabilized dipole does not readily undergo 1,3-dipolar cycloaddition but ruther transfers a proton to produce a cyclic ketene N,O-acetal. The ketene acetale is unstable to moisture and upon standing is readily hydrolyzed to a gamma-keto-delta-lactone and an amine. In the absence of any significant amount of water, the ketene N,O-acetal undergoes conjugate addition with the activated ?-bond of the dipolarophile to give a zwitterion intermediate. The anionic portion of the zwitterion adds to the neighboring carbonyl group. This is followed by epoxide ring formation with charge dissipation leading to an amido-substituted spiro cyclopentenyl epoxide. In certain cases a hydroxyl lactone was also isolated and its formation can be attributed to the competitive hydrolysis of the zwitterionic intermediate. The Rh(II)-catalyzed reaction of the diazo ketoamide derived from N-benzylpiperidone with DMAD afforded two different types of cyloadducts. In addition to the spiro cyclopentenyl epoxide, a product derived from trapping of the carbonyl ylide dipole was also obtained, thereby providing additional support for the proposed mechanism.

Supramolecular chemistry and self-organization: A veritable playground for catalysis

The directed assembly of molecular building blocks into discrete supermolecules or extended supramolecular networks through noncovalent intermolecular interactions is an ongoing challenge in chemistry. This challenge may be overcome by establishing a hierarchy of intermolecular interactions that, in turn, may facilitate the edification of supramolecular assemblies. As noncovalent interactions can be used to accelerate the reaction rates and/or to increase their selectivity, the development of efficient and practical catalytic systems, using supramolecular chemistry, has been achieved during the last few decades. However, between discrete and extended supramolecular assemblies, the newly developed ?colloidal tectonics? concept allows us to link the molecular and macroscopic scales through the structured engineering of colloidal structures that can be applied to the design of predictable, versatile, and switchable catalytic systems. The main cutting-edge strategies involving supramolecular chemistry and self-organization in catalysis will be discussed and compared in this review.
