Abstract

1, 3-Bis (2', 2'-dicarboxyethyl) azulene (2), azulyl-1, 3-bis (propanoic acid)(3), 1, 3-bis (2'- carbethoxy-3'-oxo-buty1) azulene (4), 1, 3-bis (3'-oxobutyl) azulene (S), diethyl azulene-l, &dipropanoate (6), and l, &bis (3'-hydroxypropy1) azulene (7) have been synthesized via nucleophilic displacement reactions on azulyl-l, 3-bis (meth~ ltrimethylammonium) diiodide (1). Vilsmeier acylation reactions and reduction of the carbonyl groups in the 1- ...
