Abstract

Методът намира приложение във фармацевтичната промишленост за получаване на 1-карба(детиа)-цефалоспоринови антибиотици по бърз начин. 2-субституиран метилцефалоспорин 1,1-диоксид чрез свободно радикалов процес директно се превръща в желания продукт. Заместителят в 2-субституирания метилцефалоспорин е източник на свободен радикал, например фенилселенова група. По метода диоксидът се обработва с инициатор на свободен радикал, например триалкилкалаен хидрид, в инертен разтворител при температура 45 и 1500с. 7 претенции
