Hypervalent iodine reagents constitute a powerful tool in modern synthetic organic chemistry, promoting several important reactions. One such reaction is the ring contraction of cycloalkenes and cycloalkanones promoted by iodine(III) compounds, such as iodobenzene diacetate, iodosylbenzene, iodotoluene difluoride, and [hydroxy(tosyloxy)- iodo]benzene (Koser' s reagent). This review covers all t...

to its glycoside (arachidoside) content. On the basis of in creased excretion of phenols in the group of rats fed arachi doside, and of an increased iodine content in the phenolic fraction of the urine as compared with the control, it was sug gested that this glycoside acted as an antithyroid compound by forming molecular compounds with elemental iodine in the gland. Confirmatory evidence for t...

The iodination of organic compounds is great importance in synthetic chemistry. It opens comprehensive approaches for the synthesis various biologically active compounds. recent advances using elemental iodine or iodides, covering last thirteen years, are objective present review.

Importance of compounds investigated (loratadine, desloratadine, cetirizine dihydrochloride, levocetirizinedihydrochloride) in contemporary pharmacy causes necessity of finding the fast and easy method for their identification. The aim of this work is to find the best way of visualization of chromatographic spots in qualitative determination of compounds investigated during analysis by thin lay...

In Aurelia aurita, applied iodine induces medusa formation (strobilation). This process also occurs when the temperature is lowered. This was found to increase oxidative stress resulting in an increased production of iodine from iodide. One polyp produces several medusae (initially termed ephyrae) starting at the polyp's oral end. The spreading of strobilation down the body column is controlled...

The first stereoselective version of an iodine(III)-mediated rearrangement of arylketones in the presence of orthoesters is described. The reaction products, α-arylated esters, are very useful intermediates in the synthesis of bioactive compounds such as ibuprofen. With chiral lactic acid-based iodine(III) reagents product selectivities of up to 73 % ee have been achieved.
