Abstract

Figure 1.-Nmr spectrum of 25 (top) and of decoupled H-3, H-6 and H-4, H-5 (bottom). from the allylic protons (centered at about 7 7.64) led to an" apparent" AB resonanceg for the four vinyl protons. Again, the decoupled spectrum is consistent only with the syninietrical dienone 26. Table I summarizes the ultraviolet and infrared spectral data for the cycloalk-2- enones 16, 18, and 19, the cycloalkadienones 24-26, cyclohepta-2, 4-dienone, and ...
