Catalytic kinetic resolution of cyclic secondary amines

The catalytic resolution of racemic cyclic amines has been achieved by an enantioselective amidation reaction featuring an achiral N-heterocyclic carbene catalyst and a new chiral hydroxamic acid cocatalyst working in concert. The reactions proceed at room temperature, do not generate nonvolatile byproducts, and provide enantioenriched amines by aqueous extraction.

The influence of substitution at aromatic part of 1,2,3,4-tetrahydroisoquinoline on in vitro and in vivo 5-HT1A/5-HT2A receptor activities of its 1-adamantoyloaminoalkyl derivatives

Further structure-activity relationship (SAR) studies with the 1,2,3,4-tetrahydroisoquinoline (THIQ) class of 5-HT1A ligands led to the synthesis of new 1-adamantoyloaminoalkyl derivatives. The impact of substituent variations in the aromatic part of THIQ moiety on 5-HT1A and 5-HT2A receptor affinities, as well as in vivo functional properties of the investigated compounds were discussed. It was found that modification reduced the binding affinity for 5-HT1A receptors (in comparison with unsubstituted THIQ derivatives); however, the majority of new compounds still remained potent 5-HT1A ligands (Ki = 4.9-46 nM) and most of them showed features of partial agonists of postsynaptic 5-HT1A receptors. At the same time, their 5-HT2A receptor affinity was slightly increased (Ki = 40-1475 nM), which resulted in a loss of 5-HT2A/5-HT1A selectivity. 5-Br,8-OCH3 derivative – the most potent, mixed 5-HT1A/5-HT2A ligand – produced activation of presynaptic 5-HT1A receptors and showed properties of a 5-HT2A receptor antagonist.

Construction of 1,3-Oxazolidines through a Three-Component [3+2] Cycloaddition of Tetrahydroisoquinolines, Aldehydes, and Ethyl Ketomalonate

A chemoselective and diastereoselective synthesis of fused oxazolidines was achieved by a three-component cascade reaction of tetrahydroisoquinolines (THIQs), alpha,beta-unsaturated aldehydes, and diethyl 2-oxomalonate. Probably due to the reactivity difference between the aldehyde and the ketone, the reaction proceeded through the condensation of THIQs with alpha,beta-unsaturated aldehydes and 1,3-dipolar cycloaddition of the generated azomethine ylide intermediate with 2-oxomalonate. The key features are easily available starting materials, mild reaction conditions, broad substrate scope, and high chemo- and diastereoselectivity.

Reusable, homogeneous water soluble photoredox catalyzed oxidative dehydrogenation of N-heterocycles in a biphasic system: Application to the synthesis of biologically active natural products

Herein, a simple and efficient method for the oxidative dehydrogenation (ODH) of tetrahydro-beta-carbolines, indolines and tetrahydro-(iso)quinolines is described using a reusable, homogeneous cobalt-phthalocyanine photoredox catalyst in a biphasic medium. A biphasic system offers an advantage of easy separation of the product and an efficient reusability of the homogeneous photoredox catalyst. Also, the current system significantly helps to overcome the solubility issue of the substrate and catalyst at room temperature. Its potential applications to organic transformations are demonstrated by the synthesis of various biologically active N-heterocycles such as indoles, (iso)quinolines and beta-carbolines and natural products such as eudistomin U, norharmane, and harmane and precursors to perlolyrine and flazin. Without isolation and purification, the catalyst solution can be reused up to 5 times with almost comparable reactivity. Furthermore, the efficiency of the reaction was demonstrated on a gram scale. To the best of our knowledge, this is the first report on ODH reactions using a non noble, reusable and homogeneous cobalt photoredox catalyst under environmentally friendly conditions.

Highly efficient Cu-catalyzed oxidative coupling of tertiary amines and?siloxyfurans

A mild, selective, and efficient protocol for the synthesis of gamma-aminoalkyl butenolides via the oxidative coupling between tertiary amines and siloxyfurans catalyzed by simple copper salts was developed. Compared with the reported method, our method employs copper catalyst instead of the expensive rhodium catalyst. Besides TBHP, both O2 and H2O2 can also be utilized as oxidant to effect the coupling.

Determining the scope of the lanthanide mediated, sequential hydroamination/C-C cyclization reaction: Formation of tricyclic and tetracyclic aromatic nitrogen heterocycles

The scope of the lanthanide mediated, sequential hydroamination/C-C cyclization reaction was determined for the formation of tricyclic and tetracyclic aromatic nitrogen heterocycles. An array of ring sizes was explored to determine the diastereoselectivity. The electronic characteristics of the aromatic ring was also varied to determine how it affected the cascade reaction. It was found that the benzo[a]quinolizine and the pyrido[2,1,a]isoindolizine ring systems formed with the highest diastereoselectivity (>20:1), regardless of the electronic characteristics of the aromatic ring. Additionally, a tetracyclic indole nitrogen heterocycle was formed with a 2.3:1 diastereomeric ratio. A novel procedure for substrate preparation is also presented.
