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, ...
Diastereoselective Synthesis of Piperidine Imino Sugars Using Aldol Additions of Metalated Bislactim Ethers to Threose and Erythrose Acetonides
(American Chemical Society, 2008-02-27)
[Abstract] A general strategy for the synthesis of 1-deoxy-azasugars from a chiral glycine equivalent and 4-carbon building blocks is described. Diastereoselective aldol additions of metalated bislactim ethers to matched ...
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, ...
Access to Pyrrolidine Imino Sugars via Tin(II)-Mediated Aldol Reactions of Bislactim Ethers: Synthesis of 2,5-Dideoxy-2,5-Imino-D-Glucitol
(Royal Society of Chemistry, 2008-09-05)
[Abstract] 2,5-Dideoxy-2,5-imino-D-glucitol (DGDP) has been synthesized via the tin(II)-mediated anti-selective aldol reaction of bislactim ether 5 and a 3-O-silylated 2,4-ethylidene-D-erythrose derivative 6. In accordance ...
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 ...
