Diversity-Oriented Synthesis of Bioactive Azaspirocycles

A collection of novel azaspirocyclic β-arylethylamines was prepared in good yield and excellent diastereoselectivity by an expedient strategy that features condensation of a cyclic ketone with an amino allylsilane and a tandem aza-Sakurai cyclization to generate several different spirocyclic N-heterocycles. Subsequent elaboration of the spirocyclic scaffold was achieved via Pictet-Spengler cyclizations, Suzuki cross-coupling reactions, N-functionalizations, and olefin refunctionalization reactions to create a diverse library of compounds, several of which have nanomolar affinity for the sigma 1 receptor and transmembrane protein 97 (TMEM97).

Copper-catalyzed ring-opening C(sp3)-N coupling of cycloketone oxime esters: Access to 1°, 2° and 3° alkyl amines

A novel copper-catalyzed C(sp3)-N coupling of cycloketone oxime esters with nitrogen nucleophiles has been realized. All of the N-aryl/alkylanilines, anilines and benzophenone imine could be employed in this protocol to produce a variety of 1°, 2° and 3° alkyl amines in one or two steps. These resultant cyano-containing alkyl amines were proven to be versatile synthetic building blocks in a variety of chemical transformations.

Regio- and enantioselective Baeyer-Villiger oxidation: Kinetic resolution of racemic 2-substituted cyclopentanones

A kinetic resolution of racemic 2-substituted cyclopentanones via highly regio- and enantioselective Baeyer-Villiger oxidation has been successfully developed. The reaction could afford the normal 6-substituted δ-lactones in up to 98% ee and >19/1 regioselectivity. Meanwhile, the unreacted ketones were recovered in excellent ee values (up to 98%). It represents the best results of the kinetic resolution of racemic 2-substituted cyclopentanones via nonenzymic asymmetric BV oxidation.

Highly efficient and enantioselective α-arylation of cycloalkanones by scandium-catalyzed diazoalkane-carbonyl homologation

Functionalized α-tertiary and -quaternary 2-arylcycloalkanones are rapidly accessed by scandium(III) triflate-catalyzed diazo-alkane-carbonyl homologations. Recent developments have allowed for carbon insertion reactions to be performed with catalyst loadings as low as 0.5 mol% on scales up to 5 mmol. Pairing readily available bis- and tris(oxazoline) based ligands with scandium triflate allows access to arylated medium ring carbocycles with enantioselectivities up to 98:2 er and >98% yield. The formal C-C insertion of aryldiazo-methanes into unsubstituted cycloalkanones provides a single-step solution to the ongoing challenge of α-arylation. Georg Thieme Verlag Stuttgart · New York.

Synthesis and pharmacological activity of 6-aryl-2-azabicyclo[4.2.1]nonanes

A series of 6-phenyl-, 6-(m-methoxyphenyl)- and 6-(m-hydroxyphenyl)-2-azabicylo[4.2.1]nonanes was synthesized by a sequence involving alkylation of an appropriate 2-arylcyclopentanone with an aminoalkyl substituent. Subsequent ring closure at the other α
