a-Deprotonated allyl ethers: conformational mobility and conformational preferences
Tert-BuLi is best suited to accomplish an H-metal exchange at the a-position of g-alkyl branched allyl ethers. Rapid torsional equilibration occurs at the g-terminus of the deprotonated allyl unit, while the alkoxy group at the a-site has to occupy the exo ...
1998NONCODED C-ALPHA,ALPHA-DISUBSTITUTED AMINO-ACIDS - X-RAY-DIFFRACTION ANALYSIS OF A DIPEPTIDE CONTAINING (S)-ALPHA-METHYLSERINE
The crystal and molecular structure of the fully protected dipeptide Boc-Val-(S)-alpha-MeSer-OMe has been determined by X-ray diffraction techniques. Crystals grown from ethyl acetate/n-pentane mixtures are tetragonal, space group I4(1), with cell paramete ...
1993Conformational-Analysis of Alpha-Methoxyketones - a Photoelectron Spectroscopic Investigation of 3-Methoxybicyclo[2.2.1]Heptan-2-Ones
Pierre Vogel, Annelise Carrupt
The photoelectron spectra of 3-endo-(2), of 3-exo-methoxybicyclo[2.2.1]heptan-2-one (3) and of 2-endo,3-endo-dimethoxybicyclo[2.2.1]heptane (4) are analyzed in comparison with data reported for other analogous systems and with predictions based on quantum ...
