(57) Abstract: 4-acyloxy- which is a starting material for the production of β-lactam antibiotics such as penem and carbapenem derivatives To provide a new intermediate for the synthesis of 3-hydroxyethyl-azetidinone. Formula IIIa: (Wherein, R 2 represents hydrogen or an esterifying radical, R 3 Represents a hydrogen or an acyl group of a carboxylic acid or a carbonic acid half-ester). (Wherein R 2 and R 3 have the meanings given above) or salts thereof are reduced with baker's yeast and, if desired, the obtained compound of the formula IIIa To another compound of formula IIIa according to and optionally converting the obtained free compound into a salt or the obtained salt into a free compound or another salt. |
