Beta lactam allergy and resensitization in children with suspected beta lactam allergy
Clinical and Experimental Allergy, 2009SummaryBackground In patients who were clinically diagnosed as having beta lactam allergy and had negative skin tests, the rates of reported resensitization to beta lactams after subsequent exposures, vary significantly. Some allergists advocate skin testing before every exposure to beta lactams.Objective We sought to determine the true ...

Monocyclic antibiotic .beta.-lactams
Journal of Medicinal Chemistry, 1975The preparation and antimicrobial activity of a series of beta-lactams (3a-f) are described. These compounds were prepared from the 2+2 cycloaddition of beta,beta-disubstituted enamines with aryl isocyanates; compounds 3a-f underwent facile beta-lactam ring fission between aminal carbon atom C4 and the lactam nitrogen N1.

A new synthesis of .beta.-lactams
Journal of the American Chemical Society, 1977The authors recently reported the regiospecific addition of heteroatomic nucleophiles to a number of Fp(olefin) cations (Fp = eta/sup 5/-C/sub 5/H/sub 5/Fe(CO)/sub 2/). Furthermore, it has been shown that oxidatively induced ligand transfer in FpR complexes (R-Fe-CO ..-->..
