Gas-liquid chromatographic analyses of 1,2-ethanediol monoethers and monoesters
Synthetic mixtures of saturated and unsaturated monoethers and monoesters of 1,2-ethanediol, ranging in chain length from 12 to 20, were analyzed as acetates, trifluoroacetates (TFA), and trimethylsilyl (TMS) ethers by gas chromatography on polar and ...

Effect of acute exposure of lead acetates on the morphology of liver and kidney of mice (Mus musculus) and the role of vitamin C as a repairing agent [PDF]
The objective of this study is to elicit the destructive effect of lead on the tissues of liver and kidney of mice and if vitamin C is capable of repairing the damage caused by lead. In this study, 40 male mice were used and divided into three groups as:

PdII-Catalyzed Cyclization of 1-Cyclopropyl-2-propynyl Acetates
PdCl2(MeCN)2 catalyzes the cyclization of 1-cyclopropyl-2-propynyl acetates to 3-methyl-1,4-cyclopentadienyl acetates, which are cleaved in situ to 2-cyclopentenones.

A method for the rapid qualitative and quantitative analysis of 4,4-dimethyl sterols
A simple and relatively rapid technique has been developed for the separation of several 4,4-dimethyl steryl acetates, some of which contain sterically hindered nuclear double bonds.

Substrate specific hydrolysis of aromatic and aromatic-aliphatic esters in orchid tissue cultures
We found that tissue cultures of higher plants were able, similarly as microorganisms, to transform low-molecular-weight chemical compounds. In tissue cultures of orchids (Cymbidium 'Saint Pierre' and Dendrobium phalaenopsis) acetates of phenols and ...
