Fluoronaphthyridines and -quinolones as antibacterial agents. 5. Synthesis and antimicrobial activity of chiral 1-tert-butyl-6-fluoro-7-substituted-naphthyridones
摘要:
A series of novel 7-substituted-1-tert-butyl-6-fluoronaphthyridone-3-carboxylic acids has been prepared. These derivatives are characterized by chiral aminopyrrolidine substituents at the 7 position. In this paper we report the full details of the asymmetric synthesis of this series of compounds. Structure-activity relationship studies indicate that the absolute stereochemistry at the asymmetric centers of the pyrrolidine ring is critical for maintaining good activity. Compounds 60 and 61 (3-amino-4-methylpyrrolidine enantiomers) were selected for preclinical evaluation.

Conjugate additions of aminoalcohols derived from alpha-amino acids to vinyl sulfones, followed by N-benzylation, chlorination, and intramolecular alkylation, provide a convenient route to substituted pyrrolidines. The process is accompanied by the stereospecific rearrangement of substituents from the alpha-position of the amine to the beta-position of the product and takes place via the corresponding
