Efficient Preparation of (S)- and (R)- tert -Butylmethylphosphine-Borane: A Novel Entry to Important P-Stereogenic Ligands

A novel one-pot reductive methodology for the synthesis of optically pure tert-butylmethylphosphine-borane is reported. The preparation uses as the starting material tert-butylmethylphosphinous acid-borane, which is available in both enantiomeric forms from cis-1,2-aminoindanol and tert-butyldichlorophosphine. The process is based on the reduction of a mixed anhydride, the configurational stability of which has been studied in several solvents and temperatures. Tetrabutylammonium borohydride was the best reducing agent allowing for the development of a practical process. To demonstrate the utility of the new methodology, the product obtained in this manner was used in the preparation of Quinox-P?.

Novel highly electron-deficient quinoxaline-annulated 1,3,2-diazagermol- and diazastannol-2-ylidenes, stabilized as LiCl adducts

Reaction of 2,3-bis(neopentylamino)quinoxaline (1) with nBuLi and GeCl4 or GeCl2¡¤(dioxane) (molar ratio 1:2:1) in THF furnished highly moisture-sensitive Ge(IV) and Ge(II) heterocycles 2a and 3a, respectively. The quinoxaline-annulated N-heterocyclic germylene (quinNHGe) 3a is stable only in the presence of Li(THF)x and exhibits electrophilic properties associated with the strongly electron-withdrawing annulation. Coordination of chloride at Ge(II) and of Li+ at nitrogen is assumed, as found in crystals of a bis(quinoxaline)-annulated eight-membered NHGe LiCl adduct. Addition of dineopentyl-benzimidazol-2-ylidene (bnNHC) provides a labile bnNHC-quinNHGe adduct 4 as indicated by strong downfield coordination shift of the NMR signal for the carbene donor atom. Attempts to grow single crystals led to decomposition and protonation of the carbene forming the bis(benzimidazolium) salt 5 with Li2 (THF)2 Cl42 – anion. Introduction of 2-methoxyethyl or 2-dimethylaminoethyl side arms as chelating functional groups into the diaminoquinoxalines 6 and 7 and subsequent reaction with 2 nBuLi/GeCl2¡¤(dioxane) did not markedly stabilize the resulting donor-substituted quinNHGe 8 and 9. Related silicon (2b) and tin heterocycles (3c) were synthesised for comparison. The quinoxaline-annulated N-heterocyclic stannylene 3c exhibits an extreme 119Sn upfield shift compared to other N-heterocyclic stannylenes, suggesting higher coordination at tin.

Transition-Metal-Free Decarboxylation of 3,3,3-Trifluoro-2,2-dimethylpropanoic Acid for the Preparation of C(CF3)Me2-Containing Heteroarenes

The direct synthesis of C(CF3)Me2-substituted heteroarenes by decarboxylative 1,1-dimethyltrifluoroethylation of heteroarenes with 3,3,3-trifluoro-2,2-dimethylpropanoic acid is reported. This method does not need the transition-metal catalyst, and the base is crucial for this reaction. A series of previously unknown C(CF3)Me2-containing heteroarenes were obtained in high yields and have potential applications in the drug discovery process.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: quinoxaline, you can also check out more blogs about82031-32-1

Design and synthesis of new quinoxaline derivatives as anticancer agents and apoptotic inducers

The quinoxaline scaffold is a promising platform for the discovery of active chemotherapeutic agents. Three series of quinoxaline derivatives were synthesized and biologically evaluated against three tumor cell lines (HCT116 human colon carcinoma, HepG2, liver hepatocellular carcinoma and MCF-7, human breast adenocarcinoma cell line), in addition to VEGFR-2 enzyme inhibition activity. Compounds VIId, VIIIa, VIIIc, VIIIe and XVa exhibited promising activity against the tested cell lines and weak activity against VEGFR-2. Compound VIIIc induced a significant disruption in the cell cycle profile and cell cycle arrest at the G2/M phase boundary. In further assays, the cytotoxic effect of the highly active compounds was determined using a normal Caucasian fibroblast-like fetal lung cell line (WI-38). Compound VIIIc could be considered as a lead compound that merits further optimization and development as an anti-cancer and an apoptotic inducing candidate against the HCT116 cell line.
