Abstract:
AbstractNowadays, hypervalent iodine chemistry has remarkably advanced in parallel with the emergence of novel hypervalent iodine reagents. Hypervalent iodine reagents, due to their outstanding characteristics including rich reactivities, excellent chemoselectivity, stability, and environmental friendliness, are becoming more and more popular in the synthetic organic chemistry. In this Account, a number of recent elegant research works and our perspective on the future of hypervalent iodine chemistry is presented.1 Introduction2 Recent Advances and Discussion2.1 Novel Reactivities of Hypervale

Abstract:
Hypervalent iodine reagents have been widely used in the construction of many important building blocks and privileged scaffolds of bioactive natural products. This review article aims to briefly discuss strategies that have used hypervalent iodine reagents as oxidants to synthesize spiroheterocyclic compounds and to stimulate further study for novel syntheses of spiroheterocyclic core structures using hypervalent iodine reagents under metal-free conditions.

Abstract:
The first chapter focuses on the introduction of iodine mediated carbocyclisations and their applications continue to present a stimulating challenge in target- and diversity-oriented synthesis. The second chapter discusses applications and brief literature overview about classical approaches towards the syntheses of indene derivatives. Herein the syntheses of 3-iodo-1 H-indene derivatives via iodonium-promoted 5-endo-dig carbocyclisation of 2-substituted ethynylmalonates as a key starting material are described. Within this study, we were able to show that the 3-iodo-1 H-indene can be used as

Abstract:
This thesis concerns method development of new synthetic routes by applying electrophilic hypervalent iodine reagents, such as trifluoromethyl-benziodoxole (Togni reagent) and fluoro-benziodoxole. The first project involved the addition of an oxygen moiety and trifluoromethyl group across double and triple bonds (both groups derived from the hypervalent iodine reagent). We observed that electron donating substituents on the aromatic ring of the substrate accelerated the oxytrifluoromethylation reaction. This transformation was further expanded to halo-trifluoromethylation reaction of a vinyl s

Abstract:
Dynamic isomerization of diethylstilbestrol (DES) makes it difficult to ascertain the active estrogen between its E and Z isomers. An indirect approach has been used in this project to identify the active estrogen. Methoxylated E- and Z-DES (13 and 14) and 9,10-diethylphenanthrene-3,6-diol (15), a closed ring analog of Z-DES, were synthesized and tested for their estrogenicity. The estrogenicity of 13 is higher than that of 14 and 15, which indicates that E-DES is more estrogenic than Z-DES. Dimethylstilbestrol (16), another analog of DES, was also synthesized and tested. Its estrogenicity is

Abstract:
In the first section this thesis includes the reactivity of various oxygen-containing benzofused cyclic alkenes with HTIB (Hydroxy(tosyloxy)iodobenzene). Instead of getting ring contraction products, 2H-chromene resulted in 4H-chromenes together with trans-addition products. Only cis-addition products were isolated from 4-methyl-2H-chromene. Ring contraction was observed in dihydrobenzoxepines and 2,2-dimethyl-2H-chromenes giving functionalized chromanes and benzofurans, respectively. In the second part, the ring contraction of 1,2-dihydronaphthalenes using HTIB was expanded to substrates be
