The high selectivity of the Cp2ZrHCl reducing agent for imides: A combined experimental and theoretical study on gamma-lactam and isoxazolidinone derivatives

Selective reductions of semicyclic imides either to hemiaminals (endo carbonyl reduction) or to aldehydes and amines (exo carbonyl reduction) in high yields by Schwartz’s reagent (Cp2ZrHCl) are reported. Mechanistic aspects of these reactions have been investigated at the DFT ab initio level with consideration of implicit solvent effects and thermal and pressure corrections to 298 K/1 atm. The reactions proceed from the reagents to very stable final Zr-oxo intermediates through the formation of sigma complexes and subsequent four-center transition state structures (1,2-migratory insertion). The energetic barriers for the insertion steps depend strongly on the natures of the ancillary groups at the reducing carbonyl groups. N-Carbamoyl groups are reduced to hemiaminals whereas N-acyl groups react at the exo carbonyl groups. The absence of the second carbonyl group in the simple N-methyl-2-pyrrolidone (less oxidized system) strongly reduces the thermodynamic drive for the formation of the metallocene oxo intermediate and allows an explanation of the remarkable chemoselectivity of the hydrozirconation. The zirconocene-oxo intermediates hydrolyze quickly throughout an ionic mechanism in which water molecules strongly assist the process by stabilizing ion pair separation. The computational results are consistent with a large set of experimental data on reduction of gamma-lactam and isoxazolidinone derivatives under mild conditions. They provide a way to explain and predict the relative importance of the two competitive endo/exo reduction channels of semicyclic imides by considering the electronic and steric features of substituents. Semicyclic imides such as gamma-lactam and isoxazolidinone derivatives are efficiently and selectivity reduced by the Cp2ZrHCl agent. The energetic reaction pathways for endo and exo attack, computed at the DFT level including thermal effects, allow an exhaustive interpretation of current and previously reported experimental data.

Compound design guidelines for evading the efflux and permeation barriers of Escherichia coli with the oxazolidinone class of antibacterials: Test case for a general approach to improving whole cell Gram-negative activity

Previously we reported the results from an effort to improve Gram-negative antibacterial activity in the oxazolidinone class of antibiotics via a systematic medicinal chemistry campaign focused entirely on C-ring modifications. In that series we set about testing if the efflux and permeation barriers intrinsic to the outer membrane of Escherichia coli could be rationally overcome by designing analogs to reside in specific property limits associated with Gram-negative activity: i) low MW (<400), ii) high polarity (clogD7.4 <1), and iii) zwitterionic character at pH 7.4. Indeed, we observed that only analogs residing within these limits were able to overcome these barriers. Herein we report the results from a parallel effort where we explored structural changes throughout all three rings in the scaffold for the same purpose. Compounds were tested against a diagnostic MIC panel of Escherichia coli and Staphylococcus aureus strains to determine the impact of combining structural modifications in overcoming the OM barriers and in bridging the potency gap between the species. The results demonstrated that distributing the charge-carrying moieties across two rings was also beneficial for avoidance of the outer membrane barriers. Importantly, analysis of the structure-permeation relationship (SPR) obtained from this and the prior study indicated that in addition to MW, polarity, and zwitterionic character, having ?4 rotatable bonds is also associated with evasion of the OM barriers. These combined results provide the medicinal chemist with a framework and strategy for overcoming the OM barriers in GNB in antibacterial drug discovery efforts. Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Electric Literature of 497-25-6.

Enantioselective Synthesis of Dilignol Model Compounds and Their Stereodiscrimination Study with a Dye-Decolorizing Peroxidase

A four-step enantioselective approach was developed to synthesize anti (1R,2S)-1a and (1S,2R)-1b containing a beta-O-4 linkage in good yields. A significant difference was observed for the apparent binding affinities of four stereospecific lignin model compounds with TcDyP by surface plasmon resonance, which was not translated into a significant difference in enzyme activities. The discrepancy may be attributed to the conformational change involving a loop widely present in DyPs upon H2O2 binding.
