Síntese de Calcogenofenos e Isoquinolinas via Reações de Ciclização Intramolecular
(Universidade Federal de Santa Maria, 2013-11-26)
In the first part of this work, a series of selenophenes and tellurophenes were prepared starting from of (Z)-chalcogenoenynes, by employing FeCl3 diorganyl dichalcogenide-mediated intramolecular cyclization. In general, ...
Ciclização eletrofílica intramolecular de (Z)-calcogenoeninos: síntese e reatividade de calcogenofenos e (Z)-calcogenetos vinilicos
(Universidade Federal de Santa Maria, 2019-02-22)
In the present thesis, efficient methods were developed to the synthesis of a series of heterocycles by electrophilic cyclization of (Z)-chalcogenoenynes 1, and chalcogenophenes 2, mediated by species of I2 and/or RSeBr. ...
