Reactions of 2-R-3-nitro-2H-chromenes (R=CF3, CCl3, Ph) with α-morpholinostyrene in acetonitrile proceed diastereoselectively to give mainly trans–cis-2,3,4-trisubstituted chromane enamines at room temperature and trans–trans-chromane enamines at 60 °C as a result of nucleophilic addition at...

A facile two-step synthesis of 2-methyl-1,5-dinitro-3- and 2-methyl-1,3-dinitro-5-(trifluoromethyl)benzenes is described. The first step is the nitration of otho- and para-methylbenzoic acids to furnish the corresponding dinitroacids. The dinitroacids then react with sulfur tetrafluoride to prov...

A toxicological evaluation of a novel cooling agent, 2-(4-methylphenoxy)-N-(1H-pyrazol-3-yl)-N-(2-thienylmethyl) acetamide (S2227; CAS 1374760-95-8), was completed for the purpose of assessing its safety for use in food and beverage applications. S2227 undergoes rapid oxidative metabolism in vit...

The photocatalytic TiO2-assisted decomposition of 2-(4-methylphenoxy)ethanol (MPET) in aqueous solution has been studied for the first time. The intermediate compounds of MPET photodegradation have been also determined. A toxic p-cresol is formed in significant quantities during the photocatalyt...

A toxicologic and dermatologic review of 2-(4-methylphenoxy)ethanol when used as a fragrance ingredient is presented. 2-(4-methylphenoxy)ethanol is a member of the fragrance structural group Aryl Alkyl Alcohols and is a primary alcohol. The AAAs are a structurally diverse class of fragrance ingr...

Manwuweizic acid (1), an anticancer triterpenoid isolated from Scisandra propinqua, was synthesized from lanosterol (2) by stereoselective introduction of the (Z) α,β-unsaturated carboxylic terminal of the side chain and by abnormal Beckmann rearrangement of ring A. A new reagent of DMSO-DCC-T...

When the capping of membrane immunoglobulin on spleen B cells from normal C57B1/6 mice (B6) is taken as reference, a faster capping rate is found for cells of age-matched B6 mice which are congenic at the lymphoproliferation (lpr) or nude (nu) loci. Though both congenic strains can be characteri...

An efficient synthesis of the p-toluenesulphonate salt of 3,6-dideoxy-3,6-imino 1,2-0-isopropylidene-α-D-glucofuranose (1) from glucose is reported; the potential of (1) in making hydroxylated pyrrolidines is illustrated by the preparation of 1,4-dideoxy-1,4-imino-L-gulitol, 1,4-dideoxy-1,4-imi...

The composite support CeZrYLa+LaAl was prepared by a co-precipitation method, and Pt–Rh bimetallic catalysts were fabricated on this support using different preparation procedures. The catalytic activities of these materials were tested in a gas mixture simulating the exhaust from a stoichiomet...

The Rh-catalyzed asymmetric 1,4-addition of organometallic reagents to an appropriate receptor has been a growing area of research over the last decade. The receptors for such a 1,4-addition reaction are chiefly α,β-unsaturated ketones, esters, amides, enones, nitroalkenes, and occasionally ph...

Pd–Rh/metal foam catalyst was studied for steam methane reforming and application to SOFC fuel processing. Performance of 0.068 wt% Pd–Rh/metal foam catalyst was compared with 13 wt% Ni/Al2O3 and 8 wt% Ru/Al2O3 catalysts in a tubular reactor. At 1023 K with GHSV 2000 h−1 and S/C ratio 2.5, CH4...

In the chemical industry, nitric acid and adipic acid plants are the main producers of nitrous oxide (N2O), a greenhouse gas that damages the ozone layer and leads to environmental problems. In this work, mesoporous silica KIT-6 and SBA-15-spherical, materials have been modified by post salt add...
