Title Προσπάθειες ανάπτυξης νέων αντιδραστηρίων του υπερσθενούς ιωδίου και παράγωγα αυτών με χειρόμορφα φυσικά προϊόντα
Creator Michelakis, Dimitrios
Abstract Διατμηματικό, συνεργαζόμενα Τμήματα Χημείας του Πανεπιστημίου Κρήτης και Χημείας του Αριστοτελείου Πανεπιστημίου Θεσσαλονίκης. The purpose of this thesis is the preparation of new iodanes, iodo-ylids and also the investigation of the reaction of iodonium salts with substituted and unsubstituted sodium theiophenoxide. In the first section of this thesis, new di(acyloxyiodo)benzenes were prepared from di(acetoxyiodo)benzene, in which the acetoxy- group is replaced from N-protected a-amino acids. Afterwards those new compounds were used to synthesize non natural amino acids of the general formula PhCH(OCOR)CN, when reacting with PhCh2CN. In the second section of this thesis, attempts were made to prepare new aziridines form iminoiodinanes. The iminoiodinanes were prepared from the reaction of sulfonamides and derivatives of sulfonylurea of the general formula RNHSO2NH2, with diacetoxyiodobenzene PhI(OAc)2 and iodosobenzene PhIO. In the third section of this thesis, the reaction of alkynyl iodonium salts with sodium theiophenoxide and p-chlorotheiophenoxide, was investigated. These reactions lead to the formation of isomers benzo[b]thiophenes in small yields, followed by a large amount of disulfide.
