Structure–activity relationships of the peptide deformylase inhibitor BB-3497: modification of the P2′ and P3′ side chains
摘要:
Structural modifications to the peptide deformylase inhibitor BB-3497 are described. In this paper, we describe the initial SAR around this lead for modifications to both the P2' and P3' side chains. Enzyme inhibition and antibacterial activity data revealed that a variety of substituents are tolerated at the P2' and P3' positions of the inhibitor backbone. The data from this study highlights the potential for modification at the P2' and P3' positions to optimise the physicochemical properties. (C) 2003 Elsevier Ltd. All rights reserved.

6-trimethylpyridinium hexafluorophosphate facilitated by a transient directing group. The synthetically enabling methodology constructs vicinal stereocenters with excellent regio-, diastereo-, and enantioselectivities, forging products that map onto bioactive compounds.
the presence of an L-tert-leucine-derived urea–ammonium salt as phase-transfer catalyst, a highly enantioselective alkylation of 5H-oxazol-4-ones with various benzyl bromides and allylic bromides has been developed to furnish catalytic asymmetric synthesis of biologically important dialkylated α-hydroxy carboxylic acids with a broad scope. This is the first example of an L-amino acid-derived urea–ammonium

An enantioselective vinylogous umpolung addition of deconjugated butenolides to allenoates has been developed for the first time with the help of synergistic combination of an achiral phosphine and a chiral squaramide, and represents the first example of a catalytic enantioselective Cγ–Cγ bond formation between two different carbonyl partners.
