Abstract
The invention relates to novel propargyl azetidinone compounds of the formula: <IMAGE> wherein R1 is hydrogen, alkyl, alkoxy or the R4B group, wherein R4 and B are defined in patent claims, R2 is hydrogen, alkyl or optionally substituted phenyl, R3 is hydrogen, alkyl, halogen alkyl, alkoxy methyl, aliphatic acyloxymethyl, 1-alkoxylcarbonyl oxyethyl, aralkyl, benzhydryl, phtalidyl, silyl or an allylic group and R30 is hydrogen, COOH, fluoro, chloro, bromo, iodine or trimethylsilyl or another group defined in patent claims. Compounds are useful for the preparation of 2-substituted alkyl-3-carboxy carbonemens which are useful as antibiotics and as β-lactamase-inhibitors by a novel Michael addition-elimination reaction.
