摘要：
Reaction of 3,4-dithienylmaleic anhydrides with aminoacetaldehyde dimethylacetal results in the formation of 3,4-dithienyl-substituted 1-(2,2-dimethoxyethyl)-1H-pyrrole-2,5-diones. The hydrolysis of the latter in acid medium results in the preparation of 2-[3,4-bis(thienyl)-2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl]-acetaldehydes. The obtained functionalized derivatives of maleimide demonstrate photochromic properties in solution.
