Fig. 10. Effect of chain length n on characteristic features of the products 8a–d. (a) Exponential decay of anisochronicity in the azepine CH2 groups with chain length (
in THF at 23 °C; 
f = 0.013; 
in methanol at 23 °C; 
f = 0.077); (b) exponential decay of molar ellipticity at 249 nm (
in THF at 23 °C; 
f = 0.025; 
in methanol at 23 °C; 
f = 0.076).
