4,5) Because 2 isolated from the insect was levorotatory, its absolute configuration was unambiguously assigned as R.
Accordingly, the absolute configuration of the alcohol moiety of the natural pheromone must be S.
In order to determine the absolute configuration at C-3 and also at C-13 of (1'S)-10, we synthesized all of the four stereoisomers of 10 employing the olefin cross metathesis reaction between the enantiomers of A and those of B.
28) They assigned the absolute configuration depicted as (-)-11 (Fig.
31) The absolute configuration of our (-)-11, which was prepared from (S)-citronellal, was confirmed by the X-ray analysis of the (-)ketone shown in Fig.
60) The geometries of the two double bonds and absolute configuration at C-3 of CH503 remained unknown.
68) The unique structure of 18 as a chiral allene evoked interest of chemists, and its absolute configuration was determined as R by Pirkle's synthesis of enantiomerically enriched (R)-(-)-18.
The absolute configuration of serricornin (21) was established by joint efforts of Chuman and Mori.
1974) Absolute configuration of (-)-14 methyl-8-cis-hexadecen-1-ol and methyl (-)-14methylhexadec-8-cis-enoate, the sex pheromone of female dermestid beetle.
1974) Synthesis of exo-brevicomin, the pheromone of western pine beetle, to obtain optically active forms of known absolute configuration.
Emphasising applications and real-world examples, the book begins with an overview of chirality, with a discussion of
absolute configurations and system descriptors, physical properties of enantiomers, and principles of resolution and preparation of enantiomers.
