Synthesis and biological evaluation of novel homochiral carbocyclic nucleosides from 1-amino-2-indanols

New chiral purinyl and 8-azapurinyl carbanucleoside derivatives based on indanol were synthesized from commercial available (1S,2S)-trans-1-amino-2- indanol and (1R,2R)-trans-1-amino-2-indanol using a linear methodology. The antiviral activity and cytotoxicity of these compounds were evaluated against herpes simplex virus type 1 (HSV-1) in Vero cells, bovine viral diarrhea virus (BVDV) in Mardin-Darby bovine kidney (MDBK) cells and hepatitis B virus (HBV) in HepG2 2.2.15 cell line. Three compounds, showed an inhibition of the HBsAg levels similar to reference drug lamivudine. One chloropurinyl nucleoside, derived from the cis-1-amino-2-indanol, was cytotoxic on MDBK cells and it could be a lead for developing anticancer agents.

Synthesis of alpha-CF3-substituted carbonyl compounds with relative and absolute stereocontrol using electrophilic CF3-transfer reagents

Evans-type chiral lithium imide enolates undergo diastereoselective alpha-trifluoromethylation with a hypervalent iodine-CF3 reagent with up to 91% combined isolated yield and 97:3 dr. The resulting isolated diastereopure products can be further transformed into valuable products without racemization.

Pyridine-type complexes of transition-metal halides IX. Preparation and characterization of 2,4- and 3,4-dimethylpyridine complexes of cobalt(II) bromide: The crystal structure of dibromobis(2,4-dimethylpyridine)cobalt(II) and bromotetrakis(3,4-dimethylpyridine)cobalt(II) bromide

Dibromobis(2,4-dimethylpyridine)cobalt(II) (1) crystallizes in an orthorombic (pseudo-tetragonal) space group P212121 and bromotetrakis(3,4-dimethylpyridine)cobalt(II) bromide (2) in a monoclinic space group C2/c. Cell parameters are obtained from Guinier-Haegg powder data: a=7.6742(8), b=7.6742(8), c=28.114(6) A and Z-4 for 1. and a=14.817(4), b=13.290(5),c=14.871(4) A, beta=90.55(3) and Z=4 for 2. In 1 the cobalt(II) ion is tetrahedrally coordinated with an approximate C2v symmetry, which is apparent from the infrared spectrum. In 2 the cobalt(II) ion has a rarely observed five coordination with square pyramidal geometry. The consequent spectral symmetry is C2v. The thermal decomposition pattern of samples is simple: an one-step process for 1 (DTG maximum at 335C) and a three-step process for 2, where one, one and two ligand moles are successively released (DTG maxima at 130, 193 and 360C).

Long-Range 1H-15N Heteronuclear Shift Correlation

The investigation of long-range 1H-15N heteronuclear shift correlation NMR experiments has gone from its inception in 1995 to a robust area of research with numerous studies now reported annually. The area has been reviewed twice, covering the literature through about mid-2000. The present report covers the period from where this author’s previous review stopped in late-1999 through the present. New long-range heteronuclear shift correlation methods that are applicable to long-range 1H-15N 2D heteronuclear shift correlation are discussed followed by a discussion of the impact of long-range 1H-15N data on Computer-Assisted Structure Elucidation methods and then a review of the applications of these techniques reported in the literature.

Enantio- and diastereoconvergent cyclocondensation reactions: Synthesis of enantiopure cis-decahydroquinolines

Up to four stereocenters with a well-defined configuration are generated in a single synthetic step by the cyclocondensation of (R)-phenylglycinol or (1S,2R)-1-amino-2-indanol with stereoisomeric mixtures (racemates, meso forms, diastereoisomers) of cyclohexanone-based delta-keto-acid and delta-keto-diacid derivatives in enantio- and diastereoconvergent processes that involve dynamic kinetic resolution and/or desymmetrization of enantiotopic groups. A detailed analysis of the stereochemical outcome of this process is presented. This method provides easy access to enantiopure 8- and 6,8-substituted cis-decahydroquinolines, including alkaloids of the myrioxazine family. Copyright

Glucose, cellobiose, lactose and raffinose used as chiral stationary phases in HPLC

This paper presents the enantioseparation using glucose, cellobiose, lactose and raffinose as chiral selector bonded to silica gel via an arm in HPLC. Surprisingly, they also possess high enantioseparation selectivity, may be used in normal-phase and reversed-phase mode, and there is a big chiral discriminating complementary. This work indicates that oligosaccharides could soon become very attractive as a new class of chiral stationary phase for HPLC.
