Stereoselective synthesis of alpha-monofluorinated phosphonate mimetics of naturally occurring phosphoserine and phosphothreonine, via electrophilic fluorination of lithiated bis-lactim ethers
(The Royal Society of Chemistry, 2002-06-25)[Abstract] Electrophilic fluorinations of lithiated bis-lactim ethers derived from cyclo-[L-AP4-D-Val] allow a direct access to alpha-monofluorinated phosphonate mimetics of naturally occurring phosphoserine and phosphothreonine, ... -
Synthesis of pyrrolidine homoazasugars and 3,4-dihydroxy-5-hydroxymethylprolines using aldol additions of metalated bislactim ethers to 2,4-O-ethylidene-d-erythroses
(Royal Society of Chemistry, 2009-03-27)[Abstract] A strategy for the synthesis of 2,5-dideoxy-2,5-iminohexitols and 2,5-dideoxy-2,5-iminoglyconic acids is described by using diastereoselective aldol additions of metalated bislactim ethers to 2,4-O-ethylidene- ... -
Preparation and characterization of terdentate [C,N,N] acetophenone and acetylpyridine hydrazone platinacycles: a DFT insight into the reaction mechanism
(Royal Society of Chemistry, 2017-11-13)[Abstract] The reaction of N-ortho-chlorophenyl-substituted acetylpyridine hydrazones (a and d) with K2[PtCl4] (n-butanol/water, 100 °C) gave mononuclear complexes 1a and 1d with the ligands as [N,N] bidentate. In contrast, ... -
DLPNO-CCSD(T) and DFT Study of the Acetate-Assisted C–H Activation of Benzaldimine at [RuCl2(p-cymene)]2: The Relevance of Ligand Exchange Processes at Ruthenium(II) Complexes in Polar Protic Media
(Royal Society of Chemistry (Gran Bretaña), 2024-04-25)[Abstract] To gain mechanistic insights into the acetate-assisted cyclometallations of arylimines promoted by [RuCl2(p-cymene)]2 in polar protic media, DFT geometry optimizations (with M06 and ωB97X-D3 functionals and the ...
