NiH-Catalyzed Remote Asymmetric Hydroalkylation of Alkenes with Racemic alpha-Bromo Amides

Reported here is a terminal-selective, remote asymmetric hydroalkylation of olefins with racemic alpha-bromo amides. The reaction proceeds by NiH-catalyzed alkene isomerization and subsequent alkylation reaction, and can enantioconvergently introduce an unsymmetrical secondary alkyl group from a racemic alpha-bromo amide onto a terminal C(sp3)?H position along the hydrocarbon chain of the alkene. This mild process affords a range of structurally diverse chiral alpha-alkylalkanoic amides in excellent yields, and high regio- and enantioselectivities. In addition, the synthetic utility of this protocol is further highlighted by the regioconvergent conversion of industrial raw materials of isomeric olefin mixtures into enantioriched alpha-alkylalkanoic amides on large scale.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 159635-49-1, help many people in the next few years.COA of Formula: C11H19NO2

Two novel donepezil-lipoic acid hybrids: Synthesis, anticholinesterase and antioxidant activities and theoretical studies

Alzheimer disease (AD) is a complex disease related to multiple pathogenic mechanisms. A strategy to develop effective drugs is based on the so-called multi-Target directed ligands (MTDL) by using hybrid compounds. So, in the present study, we have designed and synthesized two hybrids, containing the indanone-piperidine moiety of donepezil, a drug approved for the treatment of AD, and the lipoic acid scaffold, an antioxidant compound endowed with neuroprotective effects. One hybrid was synthesized in four steps with 42% global yield, and the other hybrid in six steps with 19% global yield. The latter hybrid displayed moderate inhibitory activity against human acetylcholinesterase (hAChE) and greater activity against human butyrylcholinesterases (hBuChE). The selectivity for hBuChE was further rationalized by theoretical study. Importantly, the second hybrid showed a good antioxidant activity, exhibiting better ability in scavenging 2,2-diphenyl- 1 picrylhydrazyl (DPPH) radicals than lipoic acid.

Synthesis of nitrogen and sulfur macrocycles with cis exogenous oxygen and sulfur donor atoms

A series of new N4 and N8 macrocycles has been prepared, that includes cis-exogenous O2, S2 and S/O atoms to allow chelation to a metal external to the macrocyclic ring. We found that thioamide units within the macrocycles were unstable to attack by secondary amines and thus alkylated precursors containing only tertiary amines could lead to exogenous-S2 macrocycles. Cyclisation of alkylated tetraamine precursors with dimethyloxalate or dithiooxamide led to both N4 and N8 macrocycles via 1 + 1 and 2 + 2 cyclisation reactions with exogenous-O2 or S2 respectively. Alkylation of preformed exogenous-O2 macrocycles was explored and led to alkyl substitution at the secondary amine nitrogens in the ring, however synthesis of these species was overall lower yielding than cyclisation using alkylated tetraamine precursors. Thionation of an exo-O2 macrocycle using an analogue of Lawesson’s Reagent led to formation of the analogous exogenous-S2 and exogenous-O,S macrocycles. Related S2N2 macrocycles with exogenous-O2: were prepared by a cyclisation route but could not be isolated free of larger ring analogues. The Royal Society of Chemistry 2005.

A New Method for the Preparation of Intermediates for 2,6-Substituted Anthrapyridazones

A new method for the preparation of 2-substituted 6-chloro-2,7-dihydro-3H-dibenzo[de,h]cynnoline-3,7-diones has been developed. The compounds have been obtained in an original three-step procedure comprising the oxidation of 1-methyl-9,10-anthraquinones with periodate or permanganate/brominating reagent systems, cyclization to 6-chloro-2,7-dihydro-3H-dibenzo[de,h]cynnoline-3,7-dione, and selective alkylation thereof. The selected processes were applied in the efficient scale-up of specific 2,6-substituted 2,7-dihydro-3H-dibenz[de,h]cinnolin-3,7-dione derivatives, currently being investigated pre-clinically as anticancer agents.

Synthesis of 2,3-Dihydro-4-pyridones, 4-Quinolones, and 2,3-Dihydro-4-azocinones by Visible-Light Photocatalytic Aerobic Dehydrogenation

The synthesis of 2,3-dihydro-4-pyridones and 4-quinolones was realized by visible-light mediated photoredox-catalyzed aerobic dehydrogenation of 4-piperidones and 2,3-dihydro-4-quinolones. This method enables the synthesis of cyclic enaminones in up to 89 % yield under mild and eco-friendly conditions and with a high tolerance of functional groups using oxygen as an inexpensive terminal oxidant and rhodamine 6G as a readily available organic photocatalyst. The process can be extended to access 2,3-dihydro-4-azocinones in up to 62 % yield via a [2+2] cycloaddition/ring-expansion sequence in a telescoping one-pot reaction. Hence, a protocol for the synthesis of three different types of N-heterocycles was developed on the same general transformation.
