SnAP reagents for the synthesis of piperazines and morpholines

Substituted piperazines and morpholines are valuable structural motifs in biologically active compounds, but are not easily prepared by contemporary cross-coupling approaches. In this report, we introduce SnAP reagents for the transformation of aldehydes into N-unprotected piperazines and morpholines. This approach offers simple, mild conditions compatible with aromatic, heteroaromatic, aliphatic, and glyoxylic aldehydes and provides mono- and disubstituted N-heterocycles in a single step.

Cytotoxic activity and DNA binding property of new aminopyrimidine derivatives

Background: Chromene and anilinopyrimidine heterocyclics are attractive anticancer compounds that have inspired many researchers to design novel derivatives bearing improved an-ticancer activity. Method: A series of pyrimidine-fused benzo[f]chromene derivatives 6a-x were synthesized as an-ticancer hybrids of 1H-benzo[f]chromenes and anilinopyrimidines. The inhibitory activity of the synthesized compounds 6a-x against cell viability of human chronic myelogenous leukemia (K562), human acute lymphoblastic leukemia (MOLT-4) and human breast adenocarcinoma (MCF-7) cell lines was evaluated using MTT assay. The interaction of the most promising compound with calf-thymus DNA was also studied using spectrometric titrations and Circular Dichro-ism (CD) spectroscopy. Results: Most compounds showed promising activity against tested cell lines. Among them, 2,4-dimethoxyanilino derivative 6g exhibited the best profile of activity against tested cell lines (IC50s = 1.6-6.1 muM) with no toxicity against NIH3T3 normal cell (IC50 >200 muM). The spectro-metric studies exhibited that compound 6g binds to DNA strongly and may change DNA conformation significantly, presumably via a groove binding mechanism. Conclusion: The results of this study suggest that the prototype compound 6g can be considered as a novel lead compound for the design and discovery of novel anticancer agents.

Amide to Alkyne Interconversion via a Nickel/Copper-Catalyzed Deamidative Cross-Coupling of Aryl and Alkenyl Amides

A nickel-catalyzed deamidative cross-coupling reaction of amides with terminal alkynes as coupling partners was disclosed. This newly developed methodology allows the direct interconversion of amides to alkynes and enables a facile route for C(sp2)-C(sp) bond formation in a straightforward and mild fashion.

2-Substituted 1-Azabicycloalkanes, a New Class of Non-Opiate Antinociceptive Agents

2-Substituted 1-azabicycloalkanes (3- and 5-aryloctahydroindolizines 2 and 11, 3-cyclohexyloctahydroindolizine 12, 4-aryloctahydroquinolizines 13, and 3-arylhexahydropyrrolizines 14) constitute a new class of non-opiate antinociceptive agents.These compounds demonstrated activity in the mouse abdominal constriction test and many were active in the mouse tail-flick test. trans-3-(2-Bromophenyl)octahydroindolizine (2a) did not bind to the opiate receptor nor did it affect arachidonate metabolism. 3-Aryloctahydroindolizines were prepared by catalytic hydrogenation of 1-aryl-3-(2-pyridinyl)-2-propen-1-ones.The X-ray crystal structure of (-)-2a was determined and absolute stereochemistry assigned as 3-R,8a-R.
