Synthesis of C-Nucleosides via Radical Coupling Reaction

Photolysis of O-acyl derivatives of N-hydroxy-2-thiopyridone, prepared from tetrahydrofuran-2-carboxylic acid, D-ribofuranosylmethanoic acid, and D-ribopyranosylmethanoic acid, gave the corresponding C-nucleoside derivatives in the presence of heteroaromatic compounds via radical pathways.The essential step in this method is a radical coupling reaction of D-ribofuranosyl radical or D-ribopyranosyl radical and some heteroaromatic bases.This is a new method for the preparation of C-nucleosides using sugar carboxylic acids.

METHOD FOR PRODUCING ESTER CONDENSED PRODUCT

The present invention is to provide a method for preparing an ester condensate and a catalyst therefor; wherein the method enables synthesis of enormous amounts of ester condensates comprising a specific structure in good yield, by a reaction of carboxylic acid and alcohol in equimolar amounts, while generation of by-products is prevented; wherein the catalyst exhibits good catalytic efficiency as a catalyst for use, the use of the catalyst in small amount is sufficient, and the catalyst is reusable and can be used repeatedly; therefore, the method for preparing an ester condensate of the present invention and the catalyst therefor can be applied to industrial methods which are preferable in view of green chemistry. Esterification reaction is performed by using a catalyst comprising a zirconium(IV) compound and/or a hafnium(IV) compound and an iron compound and a gallium compound. It is preferable that the zirconium(IV) compound is a compound represented by Zr(OH)a(OR1)b, (wherein, R1 represents an acyl group or an alkyl group, and each of a and b is 0 or any one of integers of 1 to 4 and the relationship of a + b = 4 is satisfied), and a zirconium(IV) halide.

Highly selective partial dehydrogenation of tetrahydroisoquinolines using modified Pd/C

A highly selective procedure has been developed for the partial dehydrogenation of 1-substituted-1,2,3,4-tetrahydroisoquinolines over K3PO4¡¤3H2O-modified Pd/C catalyst. This new method provides facile, atom-economical and environmentally friendly access to 1-substituted-3,4-dihydroisoquinolines without the need for stoichiometric amounts of harmful oxidants. The use of standard Pd/C as a catalyst for this process gave poor chemoselectivity. Pleasingly, the use of a K3PO4¡¤3H2O-modified Pd/C catalyst promoted the partial dehydrogenation of 1-substituted-1,2,3,4-tetrahydroisoquinolines with excellent chemoselectivity by suppressing further dehydroaromatization. Furthermore, conducting the reaction under an atmosphere of oxygen led to further improvements in the chemoselectivity of the dehydrogenation, with the ratio of imine to isoquinoline reaching up to 32/1. The heterogenous Pd/C catalyst could also be recycled and reused at least three times with excellent conversion and chemoselectivity, demonstrating the significantly practical potential of this methodology.

Chemoselective Strategy for the Direct Formation of Tetrahydro-2,5-methanobenzo[c]azepines or Azetotetrahydroisoquinolines via Regio- and Stereoselective Reactions

The present study reports regio- and highly diastereoselective preparative methods for the synthesis of versatile alkaloid-type compounds from oxiranylmethyl tetrahydroisoquinolines. 2,5-Methanobenzo[c]azepines or azetidine-fused heterocycles were synthesized in tandem reactions depending on the absence or presence of a BF3 co-reagent. A high functional group tolerance has also been demonstrated. DFT calculations with an explicit solvent model confirmed the proposed reaction mechanisms and the role of kinetic controls on the stereochemical outcome of the reported new methods.

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.

Redox-neutral alpha-sulfenylation of secondary amines: Ring-fused N,S-acetals

Secondary amines react with thiosalicylaldehydes in the presence of catalytic amounts of acetic acid to generate ring-fused N,S-acetals in redox-neutral fashion. A broad range of amines undergo alpha-sulfenylation, including challenging substrates such morpholine, thiomorpholine, and piperazines. Computational studies employing density functional theory indicate that acetic acid reduces the energy barriers of two separate steps, both of which involve proton transfer.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: tetrahydroisoquinoline, you can also check out more blogs about22990-19-8
