摘要

The synthesis of 4-alkylated monobactams by a variety of procedures is described. Two complementary procedures have been developed for the chiral synthesis of rnonobactams.(1) sulfonation of 4-alkyl-3-(protected) amino-2-azetidinones with vanous complexes of SO3, and (2) cyclization of β mesyloxyacyl sulfamates derived from β-alkyl-β- hydroxy-α-amino acids The most general procedure involves introduction of the alkyl ...
