2E,4E,6E,11Z-Octadecatetraenoic acid was synthesized in a good yield and in a stereospecific manner by coupling a vinylborane compound and ethyl trans-3-iodoacrylate. The trienic system (E,E,E) was obtained by successive use of metal-catalyzed coupling and hydro-metallation reactions.
Substituent Effects in the Intramolecular Diels-Alder Reaction of 6-Furylhexenoates
Jung, Michael E.,Kiankarimi, Mehrak
, p. 2968 - 2974 (1998)
The series of furyl enone esters, 4a-c, were synthesized from furan or furfural by straightforward routes. Their thermal intramolecular Diels-Alder reactions to give the tricyclic ketones 5a-c were studied in acetonitrile and toluene at two temperatures and the kinetics of the reactions determined. A comparison of these data with that obtained for the corresponding esters 2 to give the lactones 3 indicates that the rate enhancements seen for the esters (rate of dimethyl 310 times that of monomethyl) are much larger than those seen for the ketones (rate of dimethyl 6.8 times that of monomethyl). Thus, this is additional evidence for the earlier hypothesis that the presence of the oxygen atom in the tether is a factor responsible for the larger than normal rate enhancements.

An efficient formal total synthesis of two compounds from the selaginpulvilin family of natural products, selaginpulvilin A and C, has been successfully achieved. The tetradehydro Diels-Alder (TDDA) reaction between an enyne and alkyne has been utilized for the creation of the necessary fluorene skeleton. Attempts at the conversion of selaginpulvilin A to selaginpulvilin B, F and H were unsuccessful.
