Discovery of isoxazolinone antibacterial agents. Nitrogen as a replacement for the stereogenic center found in oxazolidinone antibacterials
摘要:
A series of potential antimicrobial derivatives possessing bioisosteric replacements for the central oxazolidinone ring found in oxazolidinone antibacterials have been prepared. The design concept involved replacement of the requisite SP3-hybridized stereogenic center found at the 5-position of the oxazolidinone with a nitrogen atom. The synthesis and antibacterial activity of three such ring systems, the benzisoxazolinones, pyrroles, and isoxazolinones is described. (C) 2004 Elsevier Ltd. All rights reserved.

Efficacious methods for the synthesis of 3-arylpyrroles or 3-pyrrolylacetylenes are described based on the palladium-catalyzed coupling of appropriate 1-(triisopropylsilyl)-3-substituted pyrroles with aryl halides or monosubstituted acetylenes and subsequent tetrabutylammonium fluoride desilylation.
