Internal Nucleophilic Termination in Acid-Mediated Polyene Cyclisations: Synthetic Access to Methyl Homologs of (+/-)-Ambrox and its Diastereoisomers

Treatment of ten monocyclic dienols 8-11 with an excess of fluorosulfonic acid in 2-nitropropane at -90 deg C afforded diastereoisomeric mixtures of racemic tricyclic ethers 12-14 in 81-91percent yield (see Tables 1 and 2).These transformations represent

STEREOCHEMISTRY OF THE CYCLIZATION OF PSEUDOIRONE AT ELEVATED TEMPERATURE

The cyclization of pseudoirone (6,9,10-trimethyl-3,5,9-undecatrien-2-one) in the presence of a catalytic amount of phosphoric acid at 110 deg C gives a high yield and leads to the preferential formation of α-irone.It was established that if the reaction was conducted in the presence of protic acids 1-(1,3,4-trimethyl-3-cyclohexenyl)-1-penten-4-one was formed in addition to the α, β, and γ isomers.
