文摘

Amino and nitro derivatives of spiropyrans based on 1-benzothieno[3,2-b]pyrrole were synthesized employing an efficient method for the reduction of nitro group in thienopyrroles and spiropyrans. Novel bi-functional compounds, containing salicylideneaniline and dithienylethene fragments, along with spiropyran were prepared from the aminospiropyran derivative.
