The enantioface-differentianing hydrogenation of 4-hydroxy-2-butanone (I) to 1,3-butanediol (II) was conduced with asymmetrically modified metal catalysts.Among the modified catalysts examined, Raney nickel modified with a solution containing tartaric acid and NaBr (TA-NaBr-MRNi) gave the best results with respect to the optical and chemical yields. (R)-II, an optical purity of 69 percent was obtained in a quantitative chemical yeld by the use of (R,R)-TA-NaBr-MRNi. (S)-II was also obtained by the use of (S,S)-TA-NaBr-MRNi.A simple method for the preparation of optically pure (S)- and (R)-II from the hydrogenation product was also developed.

Two optically active phosphoramidite monomers for modified oligodeoxyribo-nucleotides were prepared. These monomers were then introduced into dodecanucleotides in the middle of the sequences. The modified dodecanucleotides were characterized by various analytical methods including MALDI-TOF mass spectrometry and Tm values were obtained to appraise the binding affinity, by measuring change in UV absorbance at 260 nm.

The vibrational circular dichroism (VCD) spectrum (800 to 1500 cm-1) is reported for 2-methylthietane (2MT).Fixed partial charge (FPC), atomic polar tensor (APT), and charge flow (CF) methods are used to compute the VCD spectra for both stable conformers (CH3 in the axial or equatorial orientation) for the complete range of fundamental vibrations, based on 3-21G and 6-31G* harmonic force fields.The experimental and computed absorption and VCD spectra of R-(+)-2MT are compared to the previously reported spectra of R-(-)-2-methyloxetane.The success of the APT and CFmodels for reproducing the dominant ring stretching IR and VCD features of that compound is rationalized by a comparison of APT and FPC intensity expressions.Further comparison of the APT and FPC calculated electric dipole moment derivatives are interpreted to suggest values for the diagonal CS and CH stretching charge flow terms for 2MT.These investigations then provide a rationale for previously reported successes of the FPC model, and permit identification of specific vibrational modes of 2MT that are amenable to FPC-VCD modeling.The previously established conformational mixture of ca. 30percent axial and 70percent equatorial is shown to be in accord with FPC-VCD predictions for the most appropriate (beta-CH2 wagging) mode. Key words: vibrational circular dichroism, 2-methylthietane, fixed partial charge, atomic polar tensor, charge flow.

New stereodynamic diphosphinites derived from 2,2?-biphosphole, were synthesised by introduction of a linker obtained from chiral diols between the two phosphorus atoms and used for catalytic hydrogenation through a dual chirality control induced by Rh-coordination. The application of these ligands in hydrogenation of dimethyl itaconate shows that the enantioselectivity strongly depends on steric and electronic properties of the chiral linker whereas the sense of enantioselection is determined by the configuration of these stereocentres. These stereodynamic diphosphinites induce higher enantioselectivities than the analogous stereodynamic diphosphanes derived from 2,2-biphosphole. The Royal Society of Chemistry 2009.
