Pyrolysis of alpha-cellulose using a multimode microwave oven

alpha-Cellulose was pyrolyzed using a multimode microwave oven, different microwave absorbers and experimental set ups. The microwave absorber showed a strong influence: carbon gave a large gasification of cellulose (yield of gas up to 53.8%) while Al2O3 gave a high yield of bio-char (64.1%) and a low gas production (3.0%). Bio-oil was obtained with the highest yield (37.6%) using iron as microwave absorber and a condenser between the oven and the collecting system. Dark brown bio-oils having low density and viscosity due to the presence of large amount of furanosidic compounds were collected. Bio-oils were characterized through GC?MS, FT-IR, NMR, The GC?MS analysis was employed to evaluate the composition of bio-oils using calculated retention factors. A high concentration of levoglucosan (133.9 mg/mL) together with acetic acid, acetic anhydride, 1-hydroxy-2-propanone, formic acid and furfural were obtained using graphite as microwave absorber. A mechanisms was proposed to rationalize the formation of aromatic compounds present in bio-oils. Water contents in bio-oils were affected by all parameters of the process, mainly by the microwave absorber. The use of silica has proved to be a promising way to obtain bio-oil with low water content (13%), while pyrolysis in the presence of carbon gave a large amount of water (46%).

HIGH CONCENTRATION DINOTEFURAN FORMULATIONS CONTAINING METHOPRENE

A topical insecticide is provided which can be safe to use and avoids many common deleterious side effects of conventional topical insecticides. In one preferred embodiment of the invention, the active ingredient of the insecticide formulation is an amine derivative, having a nitro-methylene group, a nitroamino group or a cyanoamino group, which can be formulated to have low toxicity and excellent insecticidal activity. One particularly suitable insecticide is 1{(tetrahydro-3-furanyl)methyl}-2-nitro-3-methylguanidine (dinotefuran), an aldulticide that will kill adult fleas combined with methoprene.

Volatile composition of some red wines from Romania assessed by GC-MS

Four varietal wines Feteasc? Neagr?, Merlot, Cabernet Sauvignon and Pinot Noir from Romania were submitted to a liquid-liquid extraction with dichloromethane and analysed by gas chromatography-mass spectrometry (GC?MS). A total of 29 volatile compounds were identified and quantified over two periods of ageing. Wines were differentiated by a number of compounds, such as esters, higher alcohols, and lactones. During wine ageing, all chemicals changed in the volatile composition. Most of alcohols and acids (hexanoic and octanoic acids) increased during ageing, while the esters, except ethyl lactate and diethyl succinate, were found in lower concentrations as ageing time increased. Considering all the volatile compounds detected, esters and higher alcohols are the main contributors for Romanian red wines.

Identification of Inhibitors of the Leishmania cdc2-Related Protein Kinase CRK3

New drugs are urgently needed for the treatment of tropical parasitic diseases such as leishmaniasis and human African trypanosomiasis (HAT). This work involved a high-throughput screen of a focussed kinase set of ?3400 compounds to identify potent and parasite-selective inhibitors of an enzymatic Leishmania CRK3-cyclin6 complex. The aim of this study is to provide chemical validation that Leishmania CRK3-CYC6 is a drug target. Eight hit series were identified, of which four were followed up. The optimisation of these series using classical SAR studies afforded low-nanomolar CRK3 inhibitors with significant selectivity over the closely related human cyclin dependent kinase CDK2. Selective at last: [1,2,4]Triazolo[1,5-a]pyridines, aminopyrazoles, and disubstituted ureas were explored as potent and parasite-selective inhibitors of an enzymatic Leishmania CRK3-cyclin6 complex. Optimisation of these series using classical SAR studies afforded low-nanomolar CRK3 inhibitors with significant selectivity over the closely related human cyclin-dependent kinase CDK2.

Multicomponent reactions studies: Yonemitsu-type trimolecular condensations promoted by Ti(IV) derivatives

We have developed a Ti(IV)/Et3N-promoted trimolecular condensation of aromatic heterocycles (furan, pyrrole, imidazole, indole) with aldehydes and active methylene compounds. In the case of indole and methyl acetoacetate the reaction afforded three-component products or tricyclic cyclopenta[b]indole derivative, depending on the reaction conditions. In both cases, NMR analysis evidenced that titanium enolate is the reactive species involved in the reaction.

Highly selective one-pot conversion of THP and MOM ethers to acetates by indium triiodide-catalysed deprotection and subsequent transesterification by ethyl acetate

The chemoselective one-pot conversion of tetrahydropyranyl (THP) and methoxymethyl (MOM) ethers of primary alcohols to the corresponding acetates was presented. It was done using indium triiodide-catalysed deprotection and subsequent acetylation by ethyl acetate through a transesterification process. The advantages offered by the method included operational simplicity, ‘green’ methodology involving no toxic or hazardous chemicals and high yield.
