Synthesis of optically active 2s-, and 7s-methyl-1.6-dioxa-spiro[4.5] decane, the pheromone components of Paravespula vulgaris (L.), from S-ethyl lactate.

, p. 55 - 58 (1981)
(-)-2S, 5RS-1 and (-]-7S, 5S-2 are obtained from S-ethyl lactate 4 and their absolute configuration is thus directly correlated. Accurate enantiomeric compositions of intermediates and products were measured by complexation gas chromatography on nickel-, and manganese-bis-3-heptafluorobutyryl-1R-camphorate, 3. It could be conclusively established that the syntheses proceed with a high degree of preservation of configuration.

Optical resolution, absolute configuration, and activity of the enantiomers of proxyphylline
Selvig,Ruud Christensen,Aasen
, p. 1514 - 1518 (1983)
The enantiomers of proxyphylline have been separated via their corresponding camphanates. Synthesis of (+)-proxyphylline from theophylline and (S)-propylene oxide derived from (S)-lactic acid established the absolute configuration of the (+) and (-) isomer as S and R, respectively. The activity of the enantiomers as cyclic nucleotide phosphodiesterase inhibitors was tested in human lung tissue homogenate. No differences were found either between the two enantiomers or between the enantiomers and racemic proxyphylline.
Enantiotopic group differentiation and kinetic resolution: Asymmetric reduction of meso-1,3-dihalides
Michael Chong,Sokoll, Kenneth K.
, p. 879 - 882 (2007/10/02)
Asymmetric reduction of 1,3-dihalides derived from glycerol occurs with moderate levels of enantiotopic group differentiation. A concomitant kinetic resolution increases the enantiometric purity of the initial product.
