THERMALLY INITIATED REACTIONS OF (Z)-EPOXYHEXENYNES A FACILE PREPARATION OF 3,4-ANNULATED FURANS
Eberbach, Wolfgang,Roser, Joachim
, p. 2221 - 2234 (2007/10/02)
An efficient and general access to 3,4-annulated 2-vinylfurans (type II) is provided by the thermally induced ring transformation of epoxyhexenynes (I).Depending on the substitution pattern the reactions proceed either by heating in solution (5a-h) or under short-time thermolysis conditions (6i, j).The results are consistent with a multistep mechanism involving 1-oxacyclohepta-3,4,6-trienes as central intermediates.
Electrocyclization Rates for Some Donor-Acceptor-Substituted Trienes
Marvell, Elliot N.,Hilton, Charles,Cleary, Michael
, p. 4272 - 4275 (2007/10/02)
Three new trienes, ethyl 3-(2-vinylcyclohexenyl)-trans-propenoate (10), ethyl 3-(2-trans-styrylcyclohexenyl)-trans-propenoate (11), and ethyl 3--trans-propenoate (14), have been prepared and characterized.The kinetic
