Baylis-Hillman Acetates in Synthesis: Copper(I)/tert-Butyl Hydroperoxide Promoted One-Pot Oxidative Intramolecular Cyclization Protocol for the Preparation of Pyrrole-Fused Compounds and the Formal Synthesis of (±)-Crispine A

A convenient one-pot protocol for the synthesis of benzo-fused and indole-fused indolizines from Baylis-Hillman acetates was developed. This strategy involves CuBr/tert-butyl hydroperoxide promoted oxidation, intramolecular cyclization, and aromatization as key steps. The efficacy of this methodology was demonstrated by the formal synthesis of (±)-crispine A, a biologically active molecule.

We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 1745-07-9, and how the biochemistry of the body works.name: 6,7-Dimethoxy-1,2,3,4-tetrahydroisoquinoline

Copper(I) carboxylates of type [(nBu3P) mCuO2CR] (m = 1, 2, 3) – Synthesis, properties, and their use as CVD precursors

Copper(I) carboxylates of type [(nBu3P)mCuO 2CR] (m = 1: 3a, R = Me; 3b, R = CF3; 3c, R = Ph; 3d, R = CH=CHPh. m = 2: 4a, R = Me; 4b, R = CF3; 4c, R = Ph; 4d, R = CH= CHPh. m = 3: 8a, R = Me; 8b, R = CF3; 8c, R = CH2Ph; 8d, R = (CH 2OCH2)3H; 8e, R = cC 4H7O) are accessible by following synthesis methodologies: the reaction of [CuO2CR] (1a, R = Me; 1b, R = CF3; 1c, R = Ph; 1d, R = CH=CHPh) with m equivalents of nBu3P (2) (m = 1, 2, 3), or treatment of [(nBu3P)mCuCl] (5a, m = 1; 5b, m = 2) with [KO2CCF3] (6). A more straightforward synthesis method for 8a – 8e is the electrolysis of copper in presence of HO2CR (7a, R = Me; 7b, R = CF3; 7c, R = CH2Ph; 7d, R = (CH2OCH2)3H; 7e, R = cC 4H7O) and 2, respectively. This method allows to prepare the appropriate copper(I) carboxylate complexes in virtually quantitative yield, analytically pure form, and on an industrial scale. IR spectroscopic studies reveal that the carboxylic units in 4, 5, and 8 bind in a unidentate, chelating or mu-bridging fashion to copper(I) depending on m and R. The thermal properties of 4, 6, and 8 were determined by TG and DSC studies. Based on TG-MS experiments a conceivable mechanism for the thermally induced decomposition of these species is presented. Hot-wall Chemical Vapor Deposition experiments (CVD) with precursor 4b showed that copper could be deposited at 480C onto a TiN-coated oxidized silicon substrate. The copper films were characterized by SEM and EDX studies. Pure layers were obtained with copper particles of size 200 – 780 nm.

Aromatic sulfonamides containing a condensed piperidine moiety as potential oxidative stress-inducing anticancer agents

A 30-membered piperidine ring-fused aromatic sulfonamide library was synthetized, including N-arylsulfonyl 1,2,3,4-tetrahydroquinolines, 1,2,3,4-tetrahydroisoquinolines and 2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indoles. The compounds induced oxidative stress and glutathione depletion in HT168 melanoma and K562 leukemia cells and in micromolar concentrations exerted cytotoxic effects. Among the tested sulfonamides, compounds 21, 22, 23, 35 and 41 exhibited 100% cytotoxic effects with low (< 10 muM) EC50 values on K562 cells. The cytotoxicity of lead compound 22 was investigated in 24 different cancer cell lines, and it was found to be active against leukemia, melanoma, glioblastoma, and liver, breast and lung cancer cells, as confirmed by classical biochemical and holographic microscopic analyses.

A highly efficient heterogeneous ruthenium-catalysed oxidative alpha-cyanation of tertiary amines leading to alpha-aminonitriles

Oxidative alpha-cyanation of tertiary amines was achieved by using an MCM-41-immobilised N-alkylethylenediamine ruthenium(III) complex (MCM-41-2N-RuCl3) as catalyst in MeOH at 60 ºC in the presence of H2O2 as oxidant and NaCN in acetic acid as a cyanide source to afford the corresponding alpha-aminonitriles in good yields. The new heterogeneous ruthenium catalyst can easily be prepared by a simple two-step procedure from commercially readily available and inexpensive reagents. It can be recovered by filtration of the reaction solution and reused at least 7 times without significant loss of activity.

Visible-Light-Mediated Photocatalytic Aerobic Dehydrogenation of N-heterocycles by Surface-Grafted TiO2 and 4-amino-TEMPO

Herein, the visible-light-induced dehydrogenation of N-heterocycles such as tetrahydroquinolines, tetrahydroisoquinolines, and indolines in O2-containing suspensions of a commercially available titanium dioxide photocatalyst yielding the corresponding heteroarenes is presented. 4-Amino-2,2,6,6-tetramethylpipiridinyloxyl (4-amino-TEMPO) was found to exhibit a beneficial role, as it increased the yield and improved the selectivity of the dehydrogenation reaction. Both the selectivity and the yield are further enhanced by grafting 0.1 wt % of Ni(II) ions onto the TiO2 surface. It is proposed that the basic reactant adsorbs at Lewis acid sites present at the TiO2 surface. The dehydrogenation reaction is initiated by visible-light excitation of the resulting surface complex and a subsequent single-electron transfer from the excited N-heterocycle via the conduction band of TiO2 to O2. Ni(II) ions possibly serve as an electron transfer bridge between the conduction band of TiO2 and O2, while the TEMPO derivative is assumed to act as a selective redox mediator involved in reactions of the generated reactive oxygen species.

CuI-catalyzed C1-alkynylation of tetrahydroisoquinolines (THIQs) by A 3 reaction with tunable iminium ions

A CuI-catalyzed A3 (amines, aldehydes and alkynes) reaction of tetrahydroisoquinolines (THIQs), aldehydes, and alkynes to give C1-alkynylated THIQ products (endo-yne-THIQs) was developed. This redox neutral C1-alkynylation of THIQs, which was conducted under mild conditions, has a broad scope for the used aldehydes and alkynes. It was proposed that the A3 reaction first generates in situ exo-iminium ions, which then isomerize to endo-iminium ions and react with copper acetylides to give the endo alkynylated THIQs (endo-yne-THIQs).

Graphene-supported RuO2 nanoparticles for efficient aerobic cross-dehydrogenative coupling reaction in water

A cross-dehydrogenative coupling (CDC) reaction between tertiary amines and nitroalkanes has been realized under an oxygen atmosphere in water simply by using graphene-supported RuO2 as the catalyst, which was made from water-soluble graphene with sulfonic groups and RuCl3·nH 2O to form RuO2·nH2O nanocomposites in situ. In contrast to RuCl3·nH2O and RuO 2·nH2O, the graphene-supported RuO2 nanoparticles exhibited higher activity and stability for the aerobic CDC reaction in water.
