ON THE ESR IDENTIFICATION OF PARAMAGNETIC SPECIES OBSERVED DURING SET OXIDATION OF N,N-DIMETHYL-p-ANISIDINE

During SET oxidation of the title compound, N,N,N’-trimethyl-N’-(4-methoxyphenyl)-1,4-phenylendiamine radical cation <3a(1+)> was detected by e.s.r.; this derives from an oxidatively activated nucleophilic substitution on N,N-dimethyl-p-anisidine.Revised e.s.r. parameters for N,N-dimethyl-p-anisidinium radical are also reported.

Intramolecular dehydrogenative coupling of sp2 C-H and sp 3 C-H bonds: An expeditious route to 2-oxindoles

An intramolecular-dehydrogenative-coupling (IDC) using “transition- metal-free” oxidation conditions has been achieved to synthesize a variety of 2-oxindoles bearing an all-carbon quaternary stereogenic center at the benzylic position. The methodology involves a one-pot C-alkylation of beta-N-arylamido esters (3, 6) with alkyl halides using potassium tert-butoxide concomitant with a dehydrogenative coupling. A radical-mediated pathway has been tentatively proposed for the oxidative process.

Synthesis and structure-activity relationship studies in translocator protein ligands based on a pyrazolo[3,4-b]quinoline scaffold

As a further development of our large program focused on the medicinal chemistry of translocator protein [TSPO (18 kDa)] ligands, a new class of compounds related to alpidem has been designed using SSR180575, emapunil, and previously published pyrrolo[3,4-b]quinoline derivatives 9 as templates. The designed compounds were synthesized by alkylation of the easily accessible 4-methyl-2-phenyl-1H-pyrazolo[3,4-b]quinolin-3(2H)-one derivatives 13-15 with the required bromoacetamides. Along with the expected 2-(4-methyl-3-oxo-2- phenyl-2,3-dihydro-1H-pyrazolo[3,4-b]quinolin-1-yl)acetamide derivatives 10, 2-(4-methyl-3-oxo-2-phenyl-2H-pyrazolo[3,4-b]quinolin-9(3H)-yl)acetamide isomers 11 were isolated and characterized. The high TSPO affinity shown by new pyrazolo[3,4-b]quinoline derivatives 10 and especially 11 leads the way to further expand the chemical diversity in TSPO ligands and provides new templates and structure-affinity relationship data potentially useful in the design of new anxiolytic and neuroprotective agents.

New asymmetric synthesis of (-)-esermethole

A new synthesis of (-)-esermethole, based on the asymmetric alkylation at C(3) of racemic 1,3-dimethyl-5-methoxyoxindole (3), is described. The chloroacetyl derivatives of (-)-menthol and (S)-N-methyl-(1-phenylethyl) amine were chosen as chiral alkylating agents and used under different reaction conditions (temperature, solvent and base). In particular, the latter reacted with 3 in toluene at 10C, in the presence of t-butyllitium, giving (3S,1’S)-N-methyl-N-(1′-phenylethyl)-1,3-dimethyl-5-methoxyoxindol-3-i lacetamide (10) with a 63% d.e.. This intermediate was easily separated from the undesired minor (3R,1’S) diastereomer (11) and converted to (-)-esermethole (99.6% e.e.) in two steps.

Divergent Synthesis of Quinolones and Dihydroepindolidiones via Cu(I)-Catalyzed Cyclization of Anilines with Alkynes

A unique and efficient method for one-pot synthesis of diverse 4-quinolones from simple and readily available primary anilines and alkynes via Cu(I)-catalyzed direct cyclization has been developed. The (thio)phenols were also found to visible substrates for this reaction. Moreover, an unprecedented synthesis of dihydroepindolidiones has been demonstrated by using secondary anilines as the versatile substrates.

N -Monomethylation of amines using paraformaldehyde and H2

The selective N-monomethylation of amines is an important topic in fine chemical synthesis. Herein, for the first time, we described a selective N-monomethylation reaction of amines with paraformaldehyde and H2 in the presence of a CuAlOx catalyst. A variety of amines, including primary aromatic amines, benzylamine and cyclohexylamine, as well as secondary amines, have been shown to be compatible with this reaction.

Arylnitration of alkenes by nitration/C-H functionalization cascade using AgNO3 and HOAc

A novel arylnitration of alkenes by nitration and C-H functionalization cascade process has been developed. This methodology provides an efficient way to construct a variety of nitro-containing oxindoles and dihydroquinolin-2(1H)- ones. In addition, the process exhibits significant functional group tolerance. Moreover, the use of inexpensive and readily available starting materials makes this practical and atom-economical approach particularly attractive.

Gold(I)-catalyzed regioselective inter-/intramolecular addition cascade of di- and triynes for direct construction of substituted naphthalenes

The gold-catalyzed cascade intermolecular addition-intramolecular carbocyclization reaction of dialkynylbenzenes was developed. In this reaction, regioselective addition of an external nucleophile toward the terminal alkyne and subsequent 6-endo-dig cyclization proceeded to give the 1,3-disubstituted naphthalenes in good yields. The direct synthesis of disubstituted chrysenes via a gold-catalyzed addition and double cyclization cascade using a triyne-type substrate was also achieved.

A new method for generation of non-stabilized alpha-amino-substituted carbanions by the reaction of magnesium carbenoids with N-lithio arylamines: their reactivity and a new synthesis of alpha-amino acid derivatives

Magnesium carbenoids were generated from aryl 1-chloroalkyl sulfoxides with i-PrMgCl in THF at low temperature in quantitative yields. The magnesium carbenoids were found to be reactive with N-lithio alkylamines to afford an olefin, which was derived from dimerization of the magnesium carbenoid, in moderate yield. On the other hand, reaction of the magnesium carbenoids with N-substituted N-lithio arylamines gave non-stabilized alpha-amino-substituted carbanions in good yields. Reactivity of the alpha-amino-substituted carbanions with some electrophiles was investigated and it was found that ethyl chloroformate reacted to give alpha-amino acid derivatives in good yields. As a whole, a new method for one-pot, three-component combined synthesis of alpha-amino acid derivatives from aryl 1-chloroalkyl sulfoxides was realized.
