Polymorphism of bis(1,3-benzothiazol-2-yl) trithiocarbonate

Autor: Kevin Kafuta, Christopher Golz, Manuel Alcarazo

Publikováno v: Acta Crystallographica Section E: Crystallographic Communications, Vol 76, Iss 7, Pp 1126-1130 (2020)

The polymorphism of the title compound, C15H8N2S5, is reported, in which the (syn,syn) and (syn,anti) conformers simultaneously crystallized from a chloroform solution. The complete molecule of the (syn,syn) form is generated by a crystallographic tw

Reactivity of 5‐(Alkynyl)dibenzothiophenium Salts: Synthesis of Diynes, Vinyl Sulfones, and Phenanthrenes

Autor: Tianshu Liu, Manuel Alcarazo, Christopher Golz, Tobias Heilmann, Christian J. Rugen, Kevin Kafuta

Publikováno v: European Journal of Organic Chemistry

The reactivity of 5‐(alkynyl)dibenzothiophenium salts 1 is explored in the presence of different nucleophiles, dienes, and under photochemical conditions. Reaction with lithium acetylides affords diynes in moderate yields; while depending on the su

Protein Conjugation by Electrophilic Alkynylation Using 5-(Alkynyl)dibenzothiophenium Triflates

Autor: Tuomas P. J. Knowles, Kevin Kafuta, Gonçalo J. L. Bernardes, Manuel Alcarazo, Victor Laserna, Alena Istrate, Tuuli A. Hakala

Publikováno v: Bioconjugate Chemistry

5-(Alkynyl)dibenzothiophenium triflates are introduced as new reagents to prepare different protein conjugates through site-selective cysteine alkynylation. The protocol developed allows a highly efficient label of free cysteine-containing proteins w

Synthesis, Structure, and Reactivity of 5‐(Aryl)dibenzothiophenium Triflates

Autor: Manuel Alcarazo, Christopher Golz, André Korzun, Marvin J. Böhm, Kevin Kafuta

Publikováno v: Angewandte Chemie International Edition
Angewandte Chemie (International Ed. in English)

A synthetic protocol for the preparation of 5‐(aryl)dibenzothiophenium salts starting from inexpensive dibenzothiophene S‐oxide and simple arenes is reported. The scope of the method regarding the nature of the arene is evaluated, intermediates a
