Treatment of 1-chlorocyclobutyl p-tolyl sulfoxides with Grignard reagents such as ethylmagnesium chloride, isopropylmagnesium chloride, and cyclopentylmagnesium chloride in THF at low temperature gave cyclobutylmagnesium carbenoids in high yields. The generated magnesium carbenoids were found to be stable at -78 C for at least 30 minutes. The cyclobutylmagnesium carbenoids reacted with several nucleophiles to give multi-substituted cyclobutanes. The reaction of the cyclobutylmagnesium carbenoids with lithium alpha-sulfonyl carbanions afforded alkylidenecyclobutanes in moderate to good yields. Georg Thieme Verlag Stuttgart New York.

A new synthesis of the antimalarial clinical candidate GSK932121 is described. This approach has two key reactions, the selective acylation of an unprotected 3-hydroxymethyl-5-methyl isoxazole and the reductive N-O bond cleavage of the previously functionalized isoxazole derivative, to give the 4-(1H)pyridone ring present in the final structure. The complete synthesis consists of 5 steps (versus 10 steps in previously published reports) and has enabled the preparation of the material in kilogram scale to support clinical studies.

The relative reaction rate of five-membered heterocycles with ozone was evaluated.These relative rates were correlated to the highest bond order value in the corresponding ring, calculated by the convenient HMO model.From this correlation, the reactivity of heterocycles with ozone was able to be predicted.Also it was concluded that the predominant product in the ozonolysis of five-membered heterocycles containing an oxygen atom was the corresponding carboxylic acid, while nitrogen heterocycles gave the corresponding amide.

A new series of alpha-aminophosphonates have been synthesized by a one-pot three-component reaction of 2,3-dihydrobenzo[b][1,4]dioxine-6- carbaldehyde, various amines, and dimethyl phosphite by using nano-TiO 2 as a catalyst under solvent-free conditions at 50C. The major advantages of the present method are high yields, short reaction times, recyclable catalyst, and solvent-free reaction conditions. Among these new structurally diversified set of alpha-aminophosphonates, dimethyl (2,3-dihydrobenzo[b][1,4]dioxin-6-yl)(3-nitrophenylamino) methylphosphonate and dimethyl (2,3-dihydrobenzo[b][1,4]dioxin-6-yl)(4-fluoro-3-nitro-phenyl-amino) methylphosphonate have shown higher antioxidant activity in diphenyl picryl hydrazyl (DPPH) scavenging, reducing power assay, and lipid peroxidation methods.

Zweifel olefination is a catalyst-free reaction that serves alkene functionalization. While most methods employ commercially available boron pinacol esters, we have assembled a sequence in which the two partners of the formal coupling reaction are installed successively, starting from inexpensive boron alkoxides. The in situ formation of bisorganoborinates was accomplished by consecutive reaction of two different organometallic species. This single-pot procedure represents a great advancement in the generation of organoborinates and their involvement in C-C bond formation.

A novel series of 2-(5-methyl-1,3-diphenyl-1H-pyrazole-4-yl)-5-(5-methyl-3-phenyl-isoxazole-4-yl)-[1,3,4]-oxadiazoles were synthesized from the respective 5-methyl-N’-(5-methyl-1,3-diphenyl-1H-pyrazole-4-carbonyl)-3-phenylisoxazole-4-carbohydrazides using POCl3 at 120C or by oxidative cyclization using Burgess reagent as oxidant. Newly synthesized compounds were characterized by analytical and spectral (IR,1H NMR,13C NMR and LC?MS) methods. The synthesized compounds were evaluated for their antioxidant, antimicrobial and antidiabetic activity and were compared with standard drugs.

Based on our previous results on the ascertained potent growth inhibition effect against a panel of 60 human tumors cell lines at National Cancer Institute of Bethesda (NCI), we have synthesized a novel series of thirty-one 2-[N-methyl(R-phenyl)-aminomethyl]-3-phenyl-7-trifluoromethylquinoxalines (1-31). The lead compound 1 was previously reported to be endowed with significant inhibition against hDHFR enzyme, with a Ki of 0.2 muM. Docking studies were performed on compound 1 and here reported to predict its binding conformation to human dihydrofolate reductase (hDHFR). All compounds (1-31) were assayed versus hDHFR and human thymidylate synthase (hTS). From the screening emerged that all compounds inhibited hDHFR with Ki values included between 0.2 and 11 muM, while only a few (6, 21, 24, 27, 29) showed great activity and selectivity towards hTS. Evaluation of the anticancer activity was performed by NCI, first against the three cell line panel, and only the most active compounds (17, 21, 24, 26, 27) were evaluated on a panel of 60 human tumor cell lines. Compound 21 was the most active against all cell lines with log GI50 equal to -5.49 and log LC50 equal to -4.19 and maintained significant percent of growth inhibition on seven cancer cell lines at the concentration of 1 muM. Compound 17 was the second most active and moreover showed interesting selectivity against some cell lines (Lung cancer: A549/ATCC, Melanoma: UACC-257, Ovarian Cancer: ovcar-8 and Renal cancer: RXF 393) at all concentration examined (100-0.01 muM).
