Reaction Outcome Critically Dependent on the Method of Workup: An Example from the Synthesis of 1-Isoquinolones

A striking dependence on the method of workup has been found for annulation of benzonitriles ArCN to N-methyl 2-toluamide (1), facilitated by n-BuLi (2 equiv): Quenching the reaction by a slow addition of water produced the expected 1-isoquinolones 2; by

Nickel-Catalyzed Tandem Reaction of Functionalized Arylacetonitriles with Arylboronic Acids in 2-MeTHF: Eco-Friendly Synthesis of Aminoisoquinolines and Isoquinolones

The first example of the nickel-catalyzed tandem addition/cyclization of 2-(cyanomethyl)benzonitriles with arylboronic acids in 2-MeTHF has been developed, which provides the facile synthesis of aminoisoquinolines with good functional group tolerance under mild conditions. This chemistry has also been successfully applied to the synthesis of isoquinolones by the tandem reaction of methyl 2-(cyanomethyl)benzoates with arylboronic acids. The use of the bio-based and green solvent 2-MeTHF as the reaction medium makes the synthesis process environmentally benign. The synthetic utility of this chemistry is also indicated by the synthesis of biologically active molecules.

Highly Regioselective Isoquinoline Synthesis via Nickel-Catalyzed Iminoannulation of Alkynes at Room Temperature

A simple and cost-efficient nickel catalytic system for the annulation of 2-haloaldimines with alkynes to synthesize 3,4-disubstituted and 3-substituted isoquinolines at room temperature has been developed. The air-stable and inexpensive Ni(dppe)Cl2 was employed as a precatalyst, and Et3N was found to be an essential additive for obtaining high yields. By using this nickel catalytic system one-pot three-component direct synthesis of isoquinolines starting with simple 2-halobenzaldehydes, tert-butylamine, and alkynes were also achieved. These reactions occur in moderate to excellent yields with complete regioselectivity. Moreover, these reactions feature a broad substrate scope, easy scalability, operational simplicity, and excellent practicality.

Synthesis of some new 2,4-disubstituted hydrazinothiazoles and 2,5-disubstituted thiazolidinones

A series of hydrazinothiazoles has been synthesized by the condensation of thiosemicarbazones and α-bromoketones. Similarly the hydrazinothiazolidiones were prepared by the condensation of thiosemicarbazone and α-bromoesters. The newly synthesized compounds were characterized by NMR and LCMS studies.

New pyridine N-oxides as chiral organocatalysts in the asymmetric allylation of aromatic aldehydes

Asymmetric allylation of aromatic aldehydes 1 with allyltrichlorosilane (2) can be catalyzed by new terpene-derived bipyridine N,N′-dioxides 12-15 and an axially chiral biisoquinoline dioxide 17b with good enantioselectivities. Dioxides have been found to be more reactive catalysts than their monooxide counterparts. Crown Copyright
