Capturing a ghost. synthesis and structural characterization of Pd(dba)[P(o -Tol)3]2

In an effort to improve upon a literature synthesis of bis[tris(o-tolyl) phosphine]palladium(0) (1) from tris(o-tolyl)phosphine and Pd 2(dba)3, we instead isolated a new compound which proved to have the composition Pd(dba)[P(o-Tol)3]2 (2), upon analysis by X-ray crystallography. While this is not the first known palladium compound containing both dba and phosphine ligands, it is, to our knowledge, the first containing dba and tris(o-tolyl)phosphine. This is significant, because mixtures of Pd2(dba)3 and tris(o-tolyl)phosphine are routinely used in cross-coupling protocols, and palladium complexes containing dba and tris(o-tolyl)phosphine have been cited as intermediates in organometallic and polymerization reactions. The most interesting crystallographic parameter for 2 is an abnormally long Pd-P bond length of 2.388(1) A, which we believe is the cause of this complex’s metastability. We also present an alternative synthesis of 1 that does not require a large excess of phosphine.

Purification and characterization of L-2,3-butanediol dehydrogenase of Brevibacterium saccharolyticum C-1012 expressed in Escherichia coli

The L-2,3-butanediol dehydrogenase produced in E. coli JM109/pLBD2-CTC was purified by 5 steps. The molecular mass of this enzyme was estimated at 110 kDa and the subunit was measured to be 30 KDa. The L-BDH had some differences from the BDHs from other sources in substrate specificity, pI value, pH stability, effects of divalent cations, and organic acids.

Conversion of meso-2,3-Butanediol into 2-Butanol by Lactobacilli. Stereochemical and Enzymatic Aspects

A number of strains of Lactobacillus spp. from foods were screened for their ability to convert meso-2,3-butanediol into 2-butanol. Only three strains of L. brevis transformed the meso-diol into the secondary alcohol. These strains as well as the others unable to metabolize meso-2,3-butanediol exhibited the capacity to hydrogenate 2-butanone to 2-butanol. In both types of lactobacilli, an inverse relationship was observed between the diol or ketone concentration and the abundance of the R form of 2-butanol. This fact has been interpreted in terms of a co-occurrence of two dehydrogenases, both acting on the ketone with different kinetic parameters and opposite enantioselectivities. These results represent a further support to the assumption that 2-butanol present in distillates originates from the enzymatic activity of lactobacilli growing on mashes and give the most likely explanation of the enantiomeric excess of (R)-2-butanol generally found in distillates.

Br2 as a novel Lewis acid catalyst for Friedel-Crafts alkylation of indoles with alpha,beta-unsaturated ketones

The inexpensive Br2 can serve as a novel Lewis acid catalyst for Friedel-Crafts alkylation of indoles with alpha,beta-unsaturated ketones. Under the catalysis of only 3 mol % of Br2, this Michael addition proceeded smoothly with high efficiency and broad substrate scope. Moreover, theoretical calculations suggested that Br2 possesses only the modest power to activate chalcones and is inferior to most tested acids, indicating that acidity might not be the primary cause for the unique activity of Br2 in the current communication.

Modification of chimeric (2S, 3S)-butanediol dehydrogenase based on structural information

A chimeric (2S, 3S)-butanediol dehydrogenase (cLBDH) was engineered to have the strict (S)-configuration specificity of the (2S, 3S)-BDH (BsLBDH) derived from Brevibacterium saccharolyticum as well as the enzymatic stability of the (2R, 3S)-BDH (KpMBDH) from Klebsiella pneumonia by swapping the domains of two native BDHs. However, while cLBDH possesses the stability, it lacks the specificity. In order to assist in the design a BDH having strict substrate specificity, an X-ray structural analysis of a cLBDH crystal was conducted at 1.58 A. The results obtained show some readily apparent differences around the active sites of cLBDH and BsLBDH. Based on this structural information, a novel (2S, 3S)-BDH having a preferred specificity was developed by introducing a V254L mutation into cLBDH. The influence of this mutation on the stability of cLBDH was not evaluated. Nevertheless, the technique described herein is an effective method for the production of a tailor-made BDH.

Oxygen as single oxidant for two steps: Base-free one-pot Pd(ii)-catalyzed alcohol oxidation & arylation to halogen-intact beta-aryl alpha,beta-enones

Using oxygen as the sole oxidant for two steps, we developed a new method to synthesize beta-aryl alpha,beta-enones by fine-tuning the Pd(ii)-catalyzed oxidation of allyl alcohol to subsequent arylation with arylboronic acids, arylboronic ester and aryltrifluoroborate salt. This one-pot green method does not require copper salt, base, and intermediate isolation. Halogen-bearing chalcones, dibenzylideneacetones and arylalkyl enones were synthesized in good yields.
