3-O-Benzyl-6-O-benzoyl-1,2-O-isopropilidene-5-C-nitromethyl-a-d-glucofuranose
The title compound, C(24)H(27)NO(9), is one of the epimers of the Henry reaction of 3-O-benzyl-6-O-benzoyl-2-O-isopropyl-idene-a-d-glucofuran-5-one with nitro-methane. The conformation of the five membered rings is as expected from the precursor compound and the mol-ecule is folded with a dihedral angle of 51.4 (2)° between the aromatic rings. One O-H⋯O hydrogen bond and some intra-molecular an...
متن کاملSynthesis of 3-deoxy-3,4-didehydro derivatives of 5-O-mycaminosyltylonolide, 5-O-(4-deoxymycaminosyl) tylonolide, and desmycosin.
The 3-deoxy-3,4-didehydro derivatives of 5-O-mycaminosyltylonolide, 5-O-(4-deoxymycaminosyl)tylonolide, and desmycosin have been prepared by treatment of the corresponding 3-O-sulfonyl derivatives with NaI in 2-butanone as the key step. The mechanistic difference in the formation of the 2,3- and 3,4-unsaturated derivatives from the same 3-O-sulfonyl derivative is discussed.
متن کامل3-Benzyl-5-bromopyrazin-2(1H)-one
In the title compound, C(11)H(9)BrN(2)O, the mol-ecules are linked into R(2) (2)(8) dimers by paired N-H⋯O hydrogen bonds and these dimers are further stacked into columns along the c axis by π-π inter-actions between pyrazinone rings [centroid-centroid distance = 3.544 Å; the dihedral angle between the planes of these rings is 7.51 (16)°]. The title compound is a precursor for agents with pote...
متن کامل5'-Nor carbocyclic 5'-deoxy-5'-(isobutylthio)adenosine and a 2',3'-dideoxy-2',3'-didehydro derivative.
The inhibition of biochemical processes requiring S-adenosylmethionine as a co-factor have led to many nucleoside-based medicinal agents. Included in this group are 5'-deoxy-5'-(isobutylthio)adenosine (SIBA), a nucleoside with antiparasitic, antiviral and antiproliferative effects, and 5'-noraristeromycin, a carbocyclic-derived nucleoside with potent antiviral properties. This report brings tog...
متن کاملPoly[diaqua(μ4-3,5-dicarboxylatopyrazol-1-ido-κ6 N 1,O 5:N 2,O 3:O 3′:O 5,O 5′)lanthanum(III)]
In the title coordination polymer, [La(C(5)HN(2)O(4))(H(2)O)(2)](n), the lanthanum(III) metal centre is nine-coordinated, with a distorted tricapped trigonal prismatic geometry, by the O atoms of two water mol-ecules and by two N and five O atoms of two N,O-bidentate, one O,O'-bidentate and one O-mono-dentate 3,5-dicarb-oxyl-ato-pyra-zol-1-ide ligands. The polymeric three-dimensional structure ...
