An electrochromic composition has an anodic electrochromic compound and a cathodic electrochromic compound, in which the anodic electrochromic compound is represented by General Formula [1] shown in Claim 1 and the cathodic electrochromic compound is represented by General Formula [2] shown in Claim 1. In General Formula 1, A1 to A4 represent substituents, R1 and R2, and R20 and R21 represent a hydrogen atom or a substituent. n is an integer of 1 to 5. X represents a thiophene derivative and Y- represents an anion.
Total Synthesis of a Natural Antioxidant and Structure-Activity Relationships of Related Compounds.
A total synthesis of benzodioxole derivative 1 was achieved via a palladium(0)-catalyzed cross-coupling reaction in a 68% overall yield (4 steps). A novel series of benzodioxoles bearing a variety of aromatic and heterocyclic rings was also prepared and the antioxidative activity evaluated using in vitro model systems. Structure-activity studies revealed that i) intramolecular hydrogen-bonding in the
