High yielded and selective synthesis of macrocyclic unsaturated musk compounds from unbiased dienes using reactive distillation at high concentration.

The objective of this study was to evaluate the effects of halogenated compounds, organic acids, unsaturated fatty acids and their mixtures on in vitro methane production and fermentative characteristics of mixed rumen microorganisms. Agents used in two in vitro experiments were bromoethanesulfonic acid (BES) and pyromellitic diimide (PMDI) as halogenated compound, fumarate and malate as organi...

The ring closure in unsaturated alkyl peroxy radicals can be a competitive process the atmospheric oxidation of biogenic organic compounds.

Certain organic compounds have the potential to effectively alter water ice nucleation. Research data of those organic compounds that may affect ice formation in the atmopshere is still insufficient. Among those interesting compounds are the carboxylic acids which are present in the atmosphere due to different reasons. They are formed through ozonolysis of unsaturated organic compounds and are ...

A new efficient method for the synthesis of carboacyclic nucleosides as biologically interesting compounds via aza-conjugate addition of pyrimidine nucleobases to a,β-unsaturated esters in the presence of catalytic amount of LiOH.H2O (1.2-4.8 mol%) under microwave irradiation is described. This method affords the title compounds in good to excellent yields and i...
