Notes:
The Rh-catalyzed reaction of 1,3-butadiene with ethyl 3-diazopyruvate leads, inter alia, to a dihydro-oxepinecarboxylate whose oxidation and functinal-group manipulation produce salicylates. Wittig reactions on the acylcyclopropane accompanying the dihydrooxepine yields acrylates whose pyrolyses afford cycloheptadiene-carboxylates. Oxidation and functional-group transformation produces the natural tropone, nezukone.
