Assignment of absolute stereochemistry to an insect pheromone by chiral amplification
Shi, Xiongwei,Leal, Walter S.,Meinwald, Jerrold
, p. 297 - 303 (2007/10/03)
Chiral amplification, a new strategy for determining the absolute configuration of difficultly available natural secondary alcohols or analogous amines, is described. Using this technique, the R configuration can be assigned to both components of the male
Expeditious synthesis of Mosher amides using a solid supported carbodiimide
Adamczyk, Maciej,Fishpaugh, Jeffrey R.
, p. 7171 - 7172 (2007/10/03)
A novel method of Mosher amide synthesis using a solid supported carbodiimide in CDCl3 is described. Estimation of optical purity can be promptly achieved by direct NMR analysis of the reaction solvent.
Chiral Polymethine Dyes, III. Synthesis and Spectroscopic Properties of an Unsymmetrical, Chiral Monomethine Cyanine Dye with Thiazolyl and Quinolinyl End Group
Reichardt, Christian,Budnik, Ulrich
, p. 927 - 930 (2007/10/02)
The synthesis of the unsymmetrical monomethine cyanine dye 6 in its monochiral (6a, b) and isochiral form (6c), first realized by Goetze in 1938, has been significantly improved and its spectroscopic properties have been studied.According to the synthetic
Enantioselective complexation of organic ammonium ions by simple tetracyclic podand ionophores
Wang, Xuebao,Erickson, Shawn D.,Iimori, Takamasa,Clark Still
, p. 4128 - 4137 (2007/10/02)
A series of enantiomerically pure, C2-symmetric tetracyclic podands are synthesized and studied. These host molecules have methyl substitution, which allows only a few low-energy conformations, and they form well-defined complexes with chiral a
