متن کاملNovel Iodine Mediated Carbocyclisations and Hypervalent Iodine(iii) Reagents
The first chapter focuses on the introduction of iodine m ediated carbocyclisations and their applications continue to present a stim ulating challenge in targetand diversityoriented syntheses. Literature overview of m ore than past two decades about this area of research has been highlighted by including key examples along with the ir m echanistic aspects. The second chapter discusses applicat...
متن کاملThioamination of Alkenes with Hypervalent Iodine Reagents
An efficient thioamination of alkenes mediated by iodine(III) reagents is described. The use of different sulfur nucleophiles allows the flexible synthesis of 1,2-aminothiols from alkenes. By employing chiral iodine(III) reagents, a stereoselective version of the thioamination protocol has also been developed.
متن کاملStereoselective Ketone Rearrangements with Hypervalent Iodine Reagents.
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.
متن کاملPreparation, structure, and versatile reactivity of pseudocyclic benziodoxole triflate, new hypervalent iodine reagent.
A new pseudocyclic triflate derivative of benziodoxole (IBA-OTf) was prepared and characterized by X-ray analysis. This highly electrophilic reagent readily reacts with various organic substrates to give the corresponding products in good yields. Furthermore, IBA-OTf can be used as a catalyst with m-chloroperoxybenzoic acid as the terminal oxidant.
