Ketones from Nickel-Catalyzed Decarboxylative, Non-Symmetric Cross-Electrophile Coupling of Carboxylic Acid Esters

Synthesis of the C?C bonds of ketones relies upon one high-availability reagent (carboxylic acids) and one low-availability reagent (organometallic reagents or alkyl iodides). We demonstrate here a ketone synthesis that couples two different carboxylic acid esters, N-hydroxyphthalimide esters and S-2-pyridyl thioesters, to form aryl alkyl and dialkyl ketones in high yields. The keys to this approach are the use of a nickel catalyst with an electron-poor bipyridine or terpyridine ligand, a THF/DMA mixed solvent system, and ZnCl2 to enhance the reactivity of the NHP ester. The resulting reaction can be used to form ketones that have previously been difficult to access, such as hindered tertiary/tertiary ketones with strained rings and ketones with alpha-heteroatoms. The conditions can be employed in the coupling of complex fragments, including a 20-mer peptide fragment analog of Exendin(9?39) on solid support.

Importance of Singlet Oxygen in Photocatalytic Reactions of 2-Aryl-1,2,3,4-tetrahydroisoquinolines Using Chalcogenorosamine Photocatalysts

Aerobic oxidation of 2-aryl-1,2,3,4-tetrahydroisoquinolines was achieved photocatalytically using chalcogenorosamine photocatalysts and LED irradiation. The photocatalytic aza-Henry reaction between these substrates and nitromethane was more efficient with selenorosamine and tellurorosamine photocatalysts than with thiorosamine and rosamine photocatalysts, corresponding to the propensity of the photocatalysts to generate singlet oxygen (1O2). Appropriately, yields for the photocatalytic aza-Henry reaction were greatly reduced when the reactions were conducted under a nitrogen atmosphere. The 2-aryl-1,2,3,4-tetrahydroisoquinolines were oxidized to the corresponding 2-aryl-3,4-dihydroisoquinolones 13a-13c with selenorosamine and tellurorosamine photocatalysts in 2% aqueous acetonitrile. Di-2-aryl-1,2,3,4-tetrahydroisoquinolin-1-yl peroxides 14a and 14b were shown to be intermediates in this reaction. Thiorosamine photocatalysts, which do generate 1O2 upon irradiation, did not give 2-aryl-3,4-dihydroisoquinolones. These results suggested that the exciplex between 1O2 and the chalcogen atom of the chalcogenorosamines (the corresponding pertelluoxide, perselenoxide, or persulfoxide) and/or the hydrated perchalcogenoxide [hydroxy (perhydroxy)tellurane, -selenane, or -thiane] might be an active oxidant in the formation of 13a-13c. Computational methods were employed to provide support for the observed photocatalytic reactivity of the tellurorhodamine and selenorhodamine chromophores compared to the thiorosamine chromophores. deltaG values were determined for the oxidation and hydration of 10-Te, 10-Se, and 10-S for formation of perchalcogenoxides and hydroxyl(perhydroxy)chalcogenanes, respectively. Calculations indicate formation of the pertelluroxide perselenoxide, and persulfoxide exciplex intermediates are energetically favorable. Hydration of the exciplexes of 10-Te and 10-Se have similarly small deltaG of -3.49 and 4.51 kcal/mol, respectively. However, a significantly higher deltaG value of +22.4 kcal/mol is observed for the hydration of 10-S, which suggests that this reactive intermediate is not readily formed.

One-pot functionalisation of N-substituted tetrahydroisoquinolines by photooxidation and tunable organometallic trapping of iminium intermediates

Nucleophilic trapping of iminium salts generated via oxidative functionalisation of tertiary amines is well established with stabilised carbon nucleophiles. The few reports of organometallic additions have limited scope of substrate and organometallic nucleophile. We report a novel, one-pot methodology that functionalises N – substituted tetrahydroisoquinolines by visible lightassisted photooxidation, followed by trapping of the resultant iminium ions with organometallic nucleophiles. This affords 1,2-disubstituted tetrahydroisoquinolines in moderate to excellent yields.

Cobalt(II)/ N -Hydroxyphthalimide-Catalyzed Cross-Dehydrogenative Coupling Reaction at Room Temperature under Aerobic Condition

This work reports a cobalt(II)/N-hydroxyphthalimide (NHPI)-catalyzed cross-dehydrogenative oxidative coupling of N-aryl tetrahydroisoquinolines with various pro-nucleophiles, such as indoles, nitroalkanes, and trialkylphosphites, active methylene compounds, and other nucleophiles, such as cyanide (ethyl cyanoformate), at room temperature under aerobic conditions. The present protocol is operationally simple and can be carried out without photoirradiation and under peroxide-free conditions, even on a gram scale, to afford the products in good to excellent yields. On the basis of mass spectrometry and control experiments, a catalytic reaction pathway has been proposed.

C-H functionalization of tertiary amines by cross dehydrogenative coupling reactions: Solvent-free synthesis of alpha-aminonitriles and beta-nitroamines under aerobic condition

A solvent-free synthesis of alpha-aminonitriles and beta-nitroamines by oxidative cross-dehydrogenative coupling under aerobic condition is reported. A catalytic amount of molybdenum(vi) acetylacetonoate was found to catalyze cyanation of tertiary amines to form alpha-aminonitriles, whereas vanadium pentoxide was found to promote aza-Henry reaction to furnish beta-nitroamines. Both of these environmentally benign reactions are performed in the absence of solvents using molecular oxygen as an oxidant.
