Abstract

The reaction of hydroxy-substituted benzo-15(18)-crown-5(6) ether or benzo-18-crown-6 ether with β-phenylcinnamaldehyde in the presence of titanium tetraethoxide yielded crown-annulated 2,2-diphenylbenzopyrans. The compounds are photochromic, and the spectral characteristics of their colored form are unusual for this class of chromenes.
