Iridium(III)-Catalyzed C(3)-H Alkylation of Isoquinolines via Metal Carbene Migratory Insertion

An Ir(III)-catalyzed C(3)-H alkylation of N-acetyl-1,2-dihydroisoquinolines with diverse acceptor-acceptor diazo compounds has been achieved under a single catalytic system via metal carbene migratory insertion. Moreover, further synthetic transformations of the alkylated products such as aromatization, selective decarboxylation, and decarbonylation lead to the formation of several synthetically viable isoquinoline derivatives having immense potentials.

Ruthenium-catalyzed chemo-and enantioselective hydrogenation of isoquinoline carbocycles

A chemoselective hydrogenation of isoquinoline carbocycles was achieved by using the catalyst prepared from Ru(methallyl)2(cod) and trans-chelate chiral ligand PhTRAP. The unique chemoselectivity achieved in this hydrogenation could be ascribed to the trans-chelation of the chiral ligand. The procedure for preparing the catalyst strongly affects the reproducibility of the carbocycle hydrogenation. Various 5-, 6-, 7-, and 8-substituted isoquinolines were selectively hydrogenated at their carbocycles to afford 5,6,7,8-tetrahydroisoquinolines as major products in high yields with moderate or good enantioselectivities. Some mechanistic studies suggested that the stereogenic center was created during the initial addition of H2 to the aromatic ring in the hydrogenation of 5-substituted isoquinolines. In other words, the stereochemical control was accompanied by the dearomatization.

Chemoselective One-Pot Synthesis of Functionalized Amino-azaheterocycles Enabled by COware

Functionalized bicyclic amino-azaheterocycles are rapidly accessed in a one-pot cross-coupling/reduction sequence enabled by the use of COware. Incompatible reagents are physically separated in a single reaction vessel to effect two chemoselective transformations - Suzuki-Miyaura cross-coupling and heteroarene reduction. The developed method allows access to novel heterocyclic templates, including semisaturated Hedgehog and dual PI3K/mTOR inhibitors, which show enhanced physicochemical properties compared to their unsaturated counterparts.

PYRROLO-PYRIDINE DERIVATIVES

Compounds of formula I are ligands for dopamine receptor subtypes within the body and are therefore useful in the treatment and/or prevention of disorders of the dopamine system, in particular schizophrenia. STR1 wherein Q is STR2

The Free-Radical Phenylation of Isoquinolinium Cation

Free radical phenylation of isoquinolinium cation has been effected by photolysis of phenylthallium(III)di(trifluoroacetate) in a trifluoroacetic acid solution of isoquinoline.Analysis (g.l.c. and h.p.l.c.) of the isomeric phenylisoquinoline mixture showed that the dominant product (81.1percent) was 1-phenylisoquinoline, in accordance with two published theoretical predictions

Versatile and Efficient Synthesis of Aryl-1,2,3,4-tetrahydroisoquinolines: Nickel(II) Phosphine Ligand Catalyzed Coupling of Arylmagnesium Halides to Haloisoquinolines

Dichloronickel(II) (dppp) was used as catalyst to prepare some previously unreported arylisoquinolines 3, which were in turn hydrogenated to aryl-1,2,3,4-tetrahydroisoquinolines 2.This procedure is the most direct and ef
