New protocols for controlled reduction of carboxamides to either alcohols or amines were established using a combination of sodium hydride (NaH) and zinc halides (ZnX2). Use of a different halide on ZnX2 dictates the selectivity, wherein the NaH-ZnI2 system delivers alcohols and NaH-ZnCl2 gives amines. Extensive mechanistic studies by experimental and theoretical approaches imply that polymeric zinc hydride (ZnH2)∞ is responsible for alcohol formation, whereas dimeric zinc chloride hydride (H?Zn?Cl)2 is the key species for the production of amines.

The rodent OR-I7 is an olfactory receptor exemplar activated by aliphatic aldehydes such as octanal. Normal alkanals shorter than heptanal bind OR-I7 without activating it and hence function as antagonists in vitro. We report a series of aldehydes designed to probe the structural requirements for aliphatic ligand chains too short to meet the minimum approximate 6.9 ? length requirement for receptor activation. Experiments using recombinant mouse OR-I7 expressed in heterologous cells show that in the context of short aldehyde antagonists, OR-I7 prefers binding aliphatic chains without branches, though a single methyl on carbon-3 is permitted. The receptor can accommodate a surprisingly large number of carbons (e.g. ten in adamantyl) as long as the carbons are part of a conformationally constrained ring system. A rhodopsin-based homology model of mouse OR-I7 docked with the new antagonists suggests that small alkyl branches on the alkyl chain sterically interfere with the hydrophobic residues lining the binding site, but branch carbons can be accommodated when tied back into a compact ring system like the adamantyl and bicyclo[2.2.2]octyl systems.

Bicyclonon-1-ene: Matrix Isolation and Spectroscopic Characterization of a Moderately Strained Bridgehead Olefin
Gudipati, Murthy S.,Radziszewski, Juliusz G.,Kaszynski, Piotr,Michl, Josef
, p. 3668 - 3674 (2007/10/02)
Bicyclonon-1-ene was generated in low-temperature matrices and in fluid solutions by photodecomposition of bicyclooct-1-yldiazomethane and its photorearrangement product, 3-(bicyclooct-1-yl)diazirine.It was characterized by IR and UV absorption and by 1H and 13C NMR spectroscopy.Further evidence for the proposed structure was provided by self-trapping and by the spectral effects of deuteration on the olefinic carbon.Observed IR spectra and isotopic shifts agree well with the results of semiempirical (MNDO) and ab initio (SCF/6-31G*) calculations.
Competitive C-O Cleavage, S-O Cleavage, and Electron Transfer in the LiAlH4 Reduction of Hindered Disulfonates
Wang, Shin Shin,Sukenik, Chaim N.
, p. 653 - 656 (2007/10/02)
The reaction of heterogeneous slurries of LiAlH4 with several alkanesulfonate substrates is reported.The reducible functional group(s) in each of the substrates is attached to the 1 and/or 4 position of a bicyclooctyl skeleton.The ratio of S-O to C-O bond cleavage reflects a strong transannular electronic effect and is shown to vary with changes in solvent.A new reaction leading to carbon-carbon bond cleavage is also demonstrated, and the competition among these three pathways is shown to be related to both solvent composition and to the heterogeneity of the reaction.The powerful effect of even small amounts of HMPA in THF is delineated and a possible electron-transfer mechanism is presented to account for the carbon-carbon bond cleavage product.
