Disease relevance of acetylide


High impact information on acetylide

  • Silapropargyl/silaallenyl and silylene acetylide complexes of [Cp(CO)2W]+. Theoretical study of their interesting bonding nature and formation reaction [2].
  • Unlike [(eta5-C5Me4H)2ZrH]2(mu2,eta2,eta2-N2H2), the acetylide and alkyl zirconocene diazenido complexes are thermally robust, resisting alpha-migration and N2 cleavage up to temperatures of 115 degrees C. Dinitrogen functionalization with [(eta5-C5Me4H)2Zr]2(mu2,eta2,eta2-N2) was also accomplished by addition of proton donors [3].
  • The structure of the acetylide butenyne complex, trans-[Fe(dmpe)(2)(C[triple bond]CC(6)H(4)OCH(3))(eta(1)-C(C(6)H(5))=CH(C[triple bond]CC(6)H(4)OCH(3)))] (9a) was determined by single-crystal X-ray diffraction [4].
  • The key steps are the ring opening of epoxide 5 with acetylide 8 for the construction of the C12-C13 cis double bond and a practical hydrolytic kinetic resolution (HKR) developed by Jacobsen group for the introduction the chiral center at C3 [5].
  • Lithium acetylide addition followed by glycosylation with 3-(trimethylsilyl)propargyl alcohol converted the ribonolactone to silylated diynes [6].

Biological context of acetylide

  • The key steps include a stereoselective acetylide addition and the Ag+-mediated cyclization of an alpha-allenic alcohol to construct the trans-2,5-dihydrofuran [7].
  • The approach involves the use of three very efficient Evans oxazolidinone-mediated syn-aldol condensations, a high-yielding coupling between lithium acetylide ethylenediamine complex and a tosylate followed by methylation, and selective reduction to establish the C12-C13 (E) double bond [8].

Associations of acetylide with other chemical compounds

  • Lithium acetylide addition followed by oxidation/reduction and protective group manipulation provided the reveromycin B spiroketal core 8 which was converted into the reveromycin A (1) derivative 6 in order to confirm the stereochemistry of the spiroketal segment [9].
  • This efficient convergent strategy was performed on the basis of the coupling of the acetylide of the A-ring and the triflate of the DEF-ring, oxidation of the alkyne to diketone, intramolecular diacetalization, and stereoselective reduction of the diacetal with Et3SiH-TMSOTf [10].
  • A novel chemosensor, a cyclometalated platinum(II) bipyridyl acetylide complex containing a monoazacrown moiety in the acetylide ligand, which can signal Mg(2+) specifically and display large changes both in color and in luminescence intensity upon complexation with Mg(2+), is described [11].
  • A solid-state metathesis (exchange) reaction between hexachloroethane (C(2)Cl(6)) and lithium acetylide (Li(2)C(2)) with 5% cobalt dichloride (CoCl(2)) added as an initiator produces up to 7% carbon nanotubes, as observed via transmission electron microscopy [12].
  • The corresponding relationship between 'true' GFR (C1) and approximate GFR (i.e. based only on the second exponential--C2) was C1 = -0.58 + 1.012C2 -0.0011 C2(2) ml.min-1 For any level of renal function, the error in GFR/ECF volume, expressed as lambda 2, is less than the error in GFR expressed as C2 [13].

Gene context of acetylide

  • The triflate derivatives of the A-ring and the DEF-ring fragments were connected with lithium acetylide [14].
  • The C10/C15 1,6-diol motif was installed using Carreira's asymmetric acetylide addition methodology [15].
  • These PB ligands have been used to prepare a series of complexes of the type [Re(PB)(CO)(3)Cl], [Pt(PB)(CCR)(2)](where -CCR is an acetylide ligand) and [Ru(bpy)(2)(PB)][PF(6)](2)(bpy = 2,2'-bipyridine) [16].
  • The key step of the preparation involved a diastereoselective addition of a lithium acetylide to an optically active alkynyl ketone under Cram chelation control [17].

Analytical, diagnostic and therapeutic context of acetylide

  • A novel luminescent acetylenediide-bridged tetranuclear copper(I) complex [Cu4(mu-Ph2Ppypz)4(mu 4-eta 1,eta 2-C identical to C)]-(ClO4)2 [Ph2Ppypz = 2-(diphenylphosphino-6-pyrazol-1-yl)pyridine] has been synthesized and structurally characterized by X-ray crystallography [18].
