Krief, Alain,Jeanmart, Stephane
, p. 6167 - 6168 (2007/10/03)
Methyl (d,l) trans-chrysanthemate as well as its cis-diastereoisomer have been prepared from dimethyl dimedone, one of their isomers, in a few steps and with complete control of the relative stereochemistry.
ALLYLIC STEREOCENTRE DIRECTED CYCLOPROPANATION. A NEW HIGHLY ENANTIOSELECTIVE SYNTHESIS OF HEMICARONIC ALDEHYDE
Bernardi, Anna,Scolastico, Carlo,Villa, Roberto
, p. 3733 - 3734 (2007/10/02)
isopropyledenetriphenylphosphorane reacts with oxazolidine 4 with excellent ?-face selectivity.The title compound is obtained in high optical purity after removal of the chiral auxiliary.

A preparation of trans- and cis-caronaldehyde derivatives is described by employing iodolactonization reaction as a key step.Investigation is also carried out to establish an asymmetric synthesis by employing the same methodology which allows diastereoselective formation of optically active intermediates in both enantiomeric forms from a single precursor though the degree of asymmetric induction is found to be less satisfactory.
