Herein, we report the first Pd-catalyzed enantioselective arylation of alpha-substituted gamma-lactams. Two sets of conditions were developed for this transformation, allowing for the use of either aryl chlorides or bromides as electrophiles. Utilizing a highly electron-rich dialkylphosphine ligand we have been able to construct alpha-quaternary centers in good yields (up to 91 % yield) and high enantioselectivities (up to 97 % ee).

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 10075-52-2, help many people in the next few years.SDS of cas: 10075-52-2

Schiff bases obtained from reaction of pyridoxal-5′-phosphate with n-hexylamine, L-lysine, N-acetylethylenedimaine and tris(hydroxymerthyl)-aminomethane were studied by DC and DP polarography, as a function of the pH, the amine concentration and the solution composition.I-t curves show that the electrochemical processes are diffusion-controlled in the limiting current and the apparent constants of the formation equilibrium were determined.A relation between the stability maximum of the Schiff bases and the ionization constants of the amines was observed.

The potent anti-HIV-1 activities of L-737,126 (2) and PAS sulfones prompted us to design and test against HIV-1 in acutely infected MT-4 cells a number of novel 1- and 3-benzenesulfonylindoles. Indoles belonging to the 1-benzenesulfonyl series were found poorly or totally inactive. On the contrary, some of the 3-benzenesulfonyl derivatives turned out to be as potent as 2, being endowed with potencies in the low nanomolar concentration range. In particular, (2-methylphenyl)sulfonyl (72) and (3-methylphenyl)sulfonyl (73) derivatives showed EC50 values of 1 nM. Introduction of two methyl groups at positions 3 and 5 of the phenyl ring of 2 furnished derivatives (80 and 83) which showed very potent and selective anti-HIV-1 activity not only against the wt strain, but also against mutants carrying NNRTI-resistant mutations at positions 103 and 181 of the reverse transcriptase gene.

An efficient and modified synthesis of ethyl-4-nitro/5-nitro/6-nitro and 7-nitroindole-2-carboxylates is described. Carbohydrazides of corresponding ethyl nitroindole-2-carboxylates underwent smooth one-step transformation to 1,3,4-oxadiazolyl nitroindoles (4a-l) on reaction with aromatic carboxylic acids in the presence of phosphorus oxychloride. An alternate method to synthesize 1,3,4-oxadiazolyl nitroindoles is also described. Among the newly synthesized 1,3,4-oxadiazolyl nitroindoles, a few compounds are studied for anti-inflammatory activity.
