A Novel Bicyclic Ketal Fragmentation Reaction
Bjorklund, Michael,Jun, Jong Gab,Mundy, Bradford P.
, p. 3895 - 3898 (2007/10/02)
Bicyclic ketals of the 6,8-dioxabicyclooctane series are specifically cleaved to give δ,ε-unsaturated ketones by treatment of the ketal with acetyl iodide.
APPLICATIONS OF THE TANDEM -WITTIG-OXY-COPE REARRANGEMENT TO SYNTHESIS OF exo-BREVICOMIN AND OXOCRINOL. THE SCOPE AND LIMITATION OF THE SIGMATROPIC SEQUENCES AS A SYNTHETIC METHOD FOR δ,ε-UNSATURATED KETONES
Mikami, Koichi,Nakai, Takeshi
, p. 1349 - 1352 (2007/10/02)
The synthetic utility of the title sigmatropic sequence is illustrated in the syntheses of (E)-6-nonen-2-one, a precursor of exo-brevicomin, and oxocrinol.The scope and limitation of this sequence as a synthetic method for δ,ε-unsaturated ketones are also discussed.
REACTION DES HEXADIENE-1,5 OLS-3 AVEC LE TRIFLUOROACETATE MERCURIQUE; TRANSPOSITION D'OXY-COPE A TEMPERATURE AMBIANTE.
Bluthe, Norbert,Malacria, Max,Gore, Jacques
, p. 4263 - 4266 (2007/10/02)
Tertiary 1,5-hexadien-3-ols 1 are transformed to δ-ethylene ketones 2 in 35-75 percent yield by treatment with one equivalent of mercuric trifluoroacetate and subsequent demercuration using sodium borohydride (Scheme I, Table).
