Superhydrophobic nickel/carbon core-shell nanocomposites for the hydrogen transfer reactions of nitrobenzene and N-heterocycles

In this work, catalytic hydrogen transfer as an effective, green, convenient and economical strategy is for the first time used to synthesize anilines and N-heterocyclic aromatic compounds from nitrobenzene and N-heterocycles in one step. Nevertheless, how to effectively reduce the possible effects of water on the catalyst by removal of the by-product water, and to further introduce water as the solvent based on green chemistry are still challenges. Since the structures and properties of carbon nanocomposites are easily modified by controllable construction, a one step pyrolysis process is used for controllable construction of micro/nano hierarchical carbon nanocomposites with core-shell structures and magnetic separation performance. Using various characterization methods and model reactions the relationship between the structure of NiaNCFs (nickel-nitrogen-doped carbon frameworks) and catalytic performance was investigated, and the results show that there is a positive correlation between the catalytic performance and hydrophobicity of catalysts. Besides, the possible catalytically active sites, which are formed by the interaction of pyridinic N and graphitic N in the structure of nitrogen-doped graphene with the surfaces of Ni nanoparticles, should be pivotal to achieving the relatively high catalytic performance of materials. Due to its unique structure, the obtained NiaNCF-700 catalyst with superhydrophobicity shows extraordinary performances toward the hydrogen transfer reaction of nitrobenzene and N-heterocycles in the aqueous state; meanwhile, it was also found that NiaNCF-700 still retained its excellent catalytic activity and structural integrity after three cycles. Compared with traditional catalytic systems, our catalytic systems offer a highly effective, green and economical alternative for nitrobenzene and N-heterocycle transformation, and may open up a new avenue for simple construction of structure and activity defined carbon nanocomposite heterogeneous catalysts with superhydrophobicity.

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

DEAD-Promoted Oxidative Ugi-Type Reaction Including an Unprecedented Ugi Amidation Assisted by Dicarboxylic Acids

A mild and metal-free DEAD-promoted (DEAD = diethyl azodicarboxylate) oxidative Ugi-type reaction of tertiary amines has been demonstrated. The reaction gives easy access to alpha-amino amides and imides with diverse functional groups in good isolated yields. This Ugi-type approach achieves an unprecedented synthesis of alpha-amino amide analogues with the assistance of dicarboxylic acids, and not water, for the introduction of the carbonyl oxygen atom of the amide moiety. Mechanistic studies indicated that the dicarboxylic acids may readily undergo an intramolecular annulation, instead of the Mumm rearrangement, to give the desired amide with one molecule of anhydride released.

1-magnesiotetrahydroisoquinolyloxazolines as chiral nucleophiles in stereoselective additions to aldehydes: Auxiliary optimization, asymmetric synthesis of (+)-corlumine, (+)-bicuculline, (+)-egenine, and (+)-corytensine, and preliminary 13C NMR studies of 1-lithio- and 1-magnesiotetrahydroisoquinolyloxazolines

Transmetalation of 1-lithiotetrahydroisoquinolyloxazolines with magnesium halides affords Grignard reagents that add to aldehydes with up to 80% selectivity for one of the four possible diastereomeric products. An oxazoline chiral auxiliary derived from camphor provides an optimal blend of diastereoselectivity and isomer separability. Synthetic applications of the optimal auxiliary, patterned after a literature approach in the racemic series, comprise an improved (formal) synthesis of bicuculline, egenine, and corytensine, as well as an efficient synthesis of corlumine. Preliminary NMR studies show that both 1-lithio- and 1-magnesiotetrahydroisoquinolyloxazolines are dynamic mixtures in THF solution at low temperatures. The barrier to pyramidal inversion of the secondary Grignard reagent is in the 9.8-10.1 kcal/mol range, while an upper limit of about 8.2 kcal/mol can be assigned to the barrier to the organolithium inversion.

Arylamides hybrids of two high-affinity sigma2 receptor ligands as tools for the development of PET radiotracers

1-Cyclohexyl-4-[3-(5-methoxy-1,2,3,4-tetrahydronaphthalen-1-yl)propyl] piperazine 1 (PB28) and 2-Methoxy-5-methyl-N-[4-(6,7-dimethoxy-3,4-dihydro-1H- isoquinolin-2-yl)butyl]benzamide 2 (RHM-1) represent leads for tumor diagnosis, given their high affinity at sigma2 receptors. With the purpose of obtaining good candidates for sigma2 PET tracers development, hybrid structures between 1 and 2 were designed. Excellent sigma1/ sigma2 selectivities were reached when 6,7- dimethoxytetrahydroisoquinoline was linked to an o-methoxy substituted arylamide (11a, 12a, 15a), and for these benzamides an intramolecular H-bond in the active conformation at the sigma sites, was hypothesized. However these excellent sigma2 ligands were accompanied by interaction with P-gp, which may limit their use as sigma2 receptor PET agents when tumors overexpress P-gp. Compound 15a whose P-gp interaction was just moderate represents an interesting tool for the development of sigma2 PET tracers useful in tumors overexpressing P-gp.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.
