Tatarova, L. E.,Korchagina, D. V.,Barkhash, V. A.
, p. 74 - 77 (2007/10/03)
Stable cations from 2,3,6-trimethyl-6Z,E,8E-undecadien-10-ones (cis- and trans-pseudoirones) were generated in the HSO3F-SO2FCl system fot the first time.Configuration of the conjugated C6=C7 double bond in these ketones substantiall

Schulte-Elte, Karl H.,Pamingle, Herve,Uijttewaal, Arnold P.,Snowden, Roger L.
, p. 759 - 765 (2007/10/02)
Acid-mediated cyclisation of trienone 8, readily available from 2,3-dimethylbutanal (1; five steps: 47percent yield), using fluorosulfonic acid (6.8 mol-equiv.) in 2-nitropropane at -70 deg, afforded a 14:9:1 mixture (70percent yield) of (+/-)-cis-α-irone
Stereoselective Synthesis of (+/-)-Irones
