G. Revial et al., Enantioselective synthesis of (+)-alpha-vetivone through the Michael reaction of chiral imines, TETRAHEDR-A, 11(24), 2000, pp. 4975-4983
(+)-alpha -Vetivone has been synthesised in nine steps. The absolute stereo
chemistry of the two stereogenic centres is controlled in the same key step
involving the stereoselective Michael addition of a chiral imine of 4-isop
ropylidene-2-methylcyclohexanone to phenyl crotonate. (C) 2001 Elsevier Sci
