Abstract

Results Synthesis of the Photochemical Reactants. The syntheses of the three cyclopropenes 1, 2, and 3 are outlined in Scheme I. One interesting point is that the role of light in the step converting tosylhydrazones 10 and 11 to diazepines 12 and 13, respectively, seems to be the conversion of trans to cis stereoisomer, which permits diazepine formation.
