Desulfurization of penicillins to prepare azetidinones
-
, (2008/06/13)
A process for the Raney nickel desulfurization of penicillins is described. In the process of the invention, amino penicillanic acid or derivatives thereof are reacted with Raney nickel under controlled conditions of temperature and time to yield azetidinones which are useful as intermediates for the synthesis of monocyclic beta-lactam antibiotics.
Synthesis of β-lactam antibiotics by the sulfeno-cycloamination
Ihara,Haga,Yonekura,et al.
, p. 7345 - 7352 (2007/10/02)
A novel efficient beta -lactam synthesis was achieved by two successive processes (sulfeno-cycloamination), addition of phenysulfenyl chloride to alpha , beta -unsaturated amides followed by base treatment. Key synthetic intermediates of monobactams and nocardicin derivatives were obtained via this method. construction of the 1-carbapenam ring system by the sulfenocycloamination is also described.
