Internet Electron. J. Mol. Des. 2003, 1, 000–000 Abstract In order to separate the effect of substituents into two parts, referring to the interaction of the reacting molecules and the solvation, the δ∆G, δ∆H and δ∆S reaction constants were defined and determined from the dependence of ∆G, ∆H and ∆S activation parameters on the σ substituent constants, by analogy with the Hammett equation. The ...

(R)-Proline catalyzes the amination reaction of functionalized indane carboxaldehydes and allows for the efficient enantioselective synthesis (>99% ee) of the metabotropic glutamate receptor ligands (S)-AIDA and (S)-APICA. [reaction: see text]

Diverse peptidomimetics containing N , O - or S -aminals are synthesized via a transition metal-free C–S bond cleavage and subsequent Mannich reaction.

The synthesis of the new dithiolene complexes, [{(MeOOC),C,S2}2Mo(2-S)]; and [OMo(S2C2(COOMe)2)2]2, is reported. These complexes are obtained by the reaction of dicarbomethoxyacetylene (DMA) with either [(S~)MO(S)(~~-S)~MO(S)(S~)]~or [(CS~)MO(S)(~~-S)~MO(S)(CS~)]~and [OMO(S~)~]~-, respectively. The reaction of [(S4)Mo(0)(~2-S)2Mo(O)(S2)]2with DMA results in the new dithiolene complex [{(MeOOC)2...

Wheat germ supernatant is resolved into four fractions, C3alpha, C3beta, D and A, all of which are required in addition to elongation EF1 and EF2 for tobacco mosaic virus-RNA (TMV-RNA)-catalyzed amino acid polymerization. Fractions C3beta and D function in the binding of Met-tRNAiMet to the 40 S ribosomal subunit forming an unstable 40 S-Met-tRNA1Met complex that is detected in sucrose gradient...

Chloropentane forms asymmetric ('A') and symmetric ('S') pairs on Si(100)-2×1, differing in the direction of curvature of one pentane tail. Surprisingly this renders the rate of thermal reaction of 'A' fifteen times greater than 'S' in chlorinating room-temperature silicon. Correspondingly, for electron-induced reaction the energy threshold for A is 1 eV less than for S.
