摘要: High-field nuclear magnetic resonance spectroscopy, mass spectrometry, infrared and ultraviolet spectroscopy were used to determine the structures of two novel degradation productions penicillins sodium nafcillin (1) oxacillin (2). The products compounds (2) found possess thietan-2-one (3)and (4), respectively. structure compound (4) was confirmed by chemical synthesis via independent routes. (3) single-crystal X-ray crystallography.
