p-Menthane-3-carboxaldehyde serves as an efficient chiral auxiliary in the preparation of chiral non-racemic S-alkylthiocarbamates or 5-dithiocarbonates via the 3,3-sigmatropic rearrangement of the corresponding alkylthionocarbamates or xanthates. The tra

Chiral 1,5-, 1,6-, and 1,7-dienes generated in 3-4 steps from chiral auxiliary p-menthane-3-carboxaldehyde undergo RCM with notable discrepancies in reactivity depending on the nature and number of substituents flanking the central double bond. The chiral
Stereocontrolled formation of amino acids and N-heterocycles bearing a quaternary chiral carbon
Roy, Stephanie,Spino, Claude
, p. 939 - 942 (2007/10/03)
Stereocontrolled formation of tertiary or quaternary chiral carbons bearing nitrogen was achieved using the [3,3]-sigmatropic rearrangement of cyanate to isocyanate as a key element. A short and highly selective sequence of reactions, starting from p-ment
