Simple and scalable electrochemical synthesis of 2,1-benzisoxazoles and quinoline N-oxides.

2019

Cathodic reduction of the nitro moiety and subsequent intramolecular cyclization affords different substituted 2,1-benzisoxazoles and quinoline N-oxides. This methodology allows the synthesis of two different types of heterocycles from common simple starting materials, using electrons as a sole reagent for this transformation. The electrolysis can be conducted in a very simple undivided electrolysis cell under constant current conditions. This permits working on a larger scale compared to other electrochemical methodologies and represents a significant advantage.

DDQ mediēta elektroķīmiska para-metoksibenzil aizsarggrupas šķelšana

2019

DDQ mediēta elektroķīmiska para-metoksibenzil aizsarggrupas šķelšana. Baunis, H., zinātniskā darba vadītājs Dr. chem. prof. Sūna. E. Bakalaura darbs, 50 lappuses, 27 attēli, 9 tabulas, 55 literatūras avoti, 2 pielikumi. Latviešu valodā. Bakalaura darbā izstrādāta jauna elektroķīmiska para-metoksibenzil aizsarggrupas šķelšanas metode, izmantojot 2,3-dihlor-5,6-diciāno-1,4-benzohinonu kā elektronu pārneses mediatoru. Metode piemērota para-metoksibenzil aizsargātiem funkcionalizētiem fenoliem. Sintezēti fenolu para-metoksibenzilēteri, veikta sintezēto savienojumu pierādīšana ar spektroskopijas metodēm.
