Journal ArticleDOI
Electrophilic Azido Selenenylation of Alkenes. A Simple Synthetic Route to Racemic Taxol Side Chain.
Marcello Tiecco,Lorenzo Testaferri,Andrea Temperini,Luana Bagnoli,Francesca Marini,Claudio Santi +5 more
TL;DR: In this paper, simple alkenes react with PhSeOTf and NaN3 in MeCN to afford β-phenylseleno azides as the result of a stereospecific trans addition.
Book ChapterDOI
Selectivity in Homolytic Aromatic Substitutions. Alkylations of Pyridines
TL;DR: In this article, the authors discussed factors controlling positional selectivity in homolytic aromatic substitutions and showed that selective reactions leading to different products can be effected using the same substrate and changing the polarity of the attacking radicals.
Journal ArticleDOI
Alkenyl Nitrones Cyclizations Induced by Phenylselenenyl Bromide. A Convenient Synthetic Route to 1,2‐Oxazines.
TL;DR: In this article, six-membered cyclic iminium salts were obtained for ring closure reaction products deriving by the intramolecular capture of the seleniranium intermediates by the oxygen atom.
Journal ArticleDOI
Factors Controlling the Selenium-Induced Cyclizations of Alkenyl Hydrazines to Pyridazine or Pyrrolidinamine Derivatives.
Marcello Tiecco,Lorenzo Testaferri,Francesca Marini,Claudio Santi,Luana Bagnoli,Andrea Temperini +5 more
TL;DR: In this paper, the authors show that phenylselenenenyl sulfate, produced by diphenyl diselenide, ammonium persulfate and trifluoromethanesulfonic acid, can be used to obtain hexahydropyridazine or pyrrolidinamine derivatives depending on the nature of substituent R.
Journal ArticleDOI
Ipso substitution in the reaction of acyl radicals with 2-substituted benzothiazoles
TL;DR: In this paper nucleophilic acetyl radicals react with 2-substituted benzothiazoles effecting the displacement of several groups to afford 2-acetylbenzothiazole; the reactions are proposed to occur through a homolytic aromatic substitution at the ipso position.
