Abstract
105-106" C) in 49-6996 yield. I2 NMR examination of the crude material did not reveal the presence of any terminal vinyl group which would have resulted from reaction at the allylically related carbon. Further characterization was achieved by decarboxylation to 16 (mp 110-1 12.5" C) and 17 (mp 9 1.5-92" C) and desulfonylation to 18 (mp 25-33" C) and 19 (mp 46-48" C). Observation of a 15 Hz coupling constant between the vinyl protons in 14- ...
