Abstract

Un processo per la preparazione di un composto di formula (I): (FORMULA I) nella quale ciascuno degli R1 R2, indipendentemente uno dall'altro, è idrogeno o un residuo organico, comprende le operazioni di far reagire un composto di formula (II): (FORMULA II) nella quale R1 e R2 sono come definiti precedentemente, con un iniziatore radicalico, in presenza di ossigeno molecolare, tipicamente O2 puro o aria. I composti di formula (I) sono intermedi utili per la produzione di molti antibiotici ?-lattamici utili.A process for the preparation of a compound of formula (I): (FORMULA I) in which each of the R1 R2, independently of each other, is hydrogen or an organic residue, includes the operations of reacting a compound of formula (II ): (FORMULA II) in which R1 and R2 are as previously defined, with a radical initiator, in the presence of molecular oxygen, typically pure O2 or air. Are the compounds of formula (I) useful intermediates for the production of many useful antibiotics? -Lactams.
