Direct synthesis of 3-arylpropionic acids by tetraphosphine/palladium catalysed Heck reactions of aryl halides with acrolein ethylene acetal

Through the use of [PdCl(C3H5)]2/Cis,cis, cis-1,2,3,4-tetrakis(diphenylphosphinomethyl)cyclopentane as a catalyst, a range of aryl bromides undergoes Heck reaction with acrolein ethylene acetal. With this acetal, the selective formation of 3-arylpropionic acids/esters was observed. The functional group tolerance on the aryl halide is remarkable; substituents such as fluoro, methyl, methoxy, acetyl, formyl, benzoyl, nitro or nitrile are tolerated. Furthermore, this catalyst can be used at low loading, even for reactions of sterically hindered aryl bromides. Graphical Abstract.

Synthesis of N-substituted benzo[c][1,7]- and benzo[c][1,8] phenanthrolin-(5H)-6-ones through a Pd-mediated Suzuki-Miyaura heteroaryl-aryl coupling reaction

In the course of the search for non-camptothecin topoisomerase I inhibitors we have undertaken the synthesis of N-substituted benzo[c][1,7]- and benzo[c][1,8]phenanthrolinone derivatives. An intermolecular Suzuki-Miyaura heteroaryl-aryl coupling reaction was planned as the key step. Then a nitro reduction followed by a concomitant lactamization achieved the construction of the tetracycle structures. This methodology permitted a rapid and efficient elaboration of biologically potent compounds.

New N-aryl-N?-(3-(substituted)phenyl)-N?-methylguanidines as leads to potential PET radioligands for imaging the open NMDA receptor

An expansive set of N-aryl-N?-(3-(substituted)phenyl)-N?-methylguanidines was prepared in a search for new leads to prospective PET ligands for imaging of the open channel of the N-methyl-d-aspartate (NMDA) receptor in vivo. The N-aryl rings and their substituents were varied, whereas the N-methyl group was maintained as a site for potential labeling with the positron-emitter, carbon-11 (t1/2 = 20.4 min). At micromolar concentration, over half of the prepared compounds strongly inhibited the binding of [3H]TCP to its binding site in the open NMDA receptor in vitro. Four ligands displayed affinities that are similar or superior to those of the promising SPECT radioligand ([123I]CNS1261). The 3?-dimethylamino (19; Ki 36.7 nM), 3?-trifluoromethyl (20; Ki 18.3 nM) and 3?-methylthio (2; Ki 39.8 nM) derivatives of N-1-naphthyl-N?-(phenyl)-N?-methylguanidine were identified as especially attractive leads for PET radioligand development.

Visible light-induced direct alpha C?H functionalization of alcohols

Considering the synthetic value of introducing active alcoholic hydroxyl group, developing C?H functionalization of alcohols is of significance. Herein, we present a photochemical method that under visible light irradiation, selectfluor can effectively promote the oxidative cross-coupling between alcohols and heteroarenes without the external photocatalysis, achieving the selective alpha sp3 C?H arylation of alcohol, even in the presence of ether. The N-F activation of selectfluor under blue LEDs irradiation is evidenced by electron paramagnetic resonance (EPR) study, which is the key process for the oxidative activation of alpha sp3 C?H alcohols. The observed reactivity may have significant implications for chemical transformations.

C-10 ester and ether derivatives of dihydroartemisinin – 10-alpha artesunate, preparation of authentic 10-beta artesunate, and of other ester and ether derivatives bearing potential aromatic intercalating groups at C-10

Preparative and stereochemical aspects of reactions providing new C-10 ester and ether derivatives of the antimalarial drug dihydroartemisinin (DHA, 2) have been examined. beta-Artesunate has been prepared for the first time, and has been differentiated from the antimalarial alpha-artesunate; the latter has been incorrectly designated as the beta-epimer in Chemical Abstracts and some primary literature. New ester and ether derivatives bearing potential intercalating groups have been synthesised by means of the Schmidt, Mitsunobu and DCC coupling procedures, by acylation in the presence of DMAP, or by hydroxy activation with BF3 as catalyst. When the hydroxy group of DHA acts as a nucleophile towards activated carboxy groups in acylating agents or the DCC intermediate, alpha-esters are obtained exclusively. When the hydroxy group is activated for displacement by nucleophiles, as in the Schmidt or Mitsunobu procedures, beta-esters and beta-ethers are obtained either exclusively or predominantly. An exception is represented by the Mitsunobu procedure involving DHA and 1- and 2-naphthols, in which mixtures of epimers are obtained; however, exclusive formation of beta-aryl ethers takes place when the Schmidt procedure is used, with activation of the intermediate trichloracetimidate by SnCl2. The latter method is therefore superior to patented procedures for the preparation of beta-aryl ethers from nonbasic aryl alcohols without detectable rearrangement to C-aryl compounds. However, the Mitsunobu procedure is better when basic aromatic alcohols are used as nucleophiles. The formation of alpha-products in which the hydroxy group of DHA acts as a nucleophile is of biological significance in relation to enzyme-mediated Phase II glucuronidation of DHA, in which only the alpha-DHA glucuronide is formed.

One-pot alpha-arylation of beta-carboline with indole and naphthol derivatives

4,9-Dihydro-3H-beta-carboline and 6-methoxy-4,9-dihydro-3H-beta-carboline were subjected to catalyst-free one-pot alpha-arylation with 1-or 2-naphthol, 6-hydroxyquinoline or 5-hydroxyisoquinoline as N-containing analogues via direct aza-Friedel-Crafts reactions. The procedure was then extended to other electron-rich aromatic compounds, such as indole or indole-2-carboxylic acid, to yield new indole gamma-amino acid derivatives containing beta-carboline skeleton. All the reactions were performed both under neat conditions and with microwave irradiation. The reaction of 2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole and benzaldehyde with 1-naphthol as nucleophile led to the formation of the N-alkylated compound as a single product, whereas the reaction with 2-naphtol resulted in the two possible alpha-arylated/N-alkylated products, in a ratio depending on the reaction conditions.
