Abstract

Efficient Syntheses of 3H-Azuleno[8,1-cd]pyridazines and Their Thermal and Photochemical Reactions. -A convenient one-pot procedure is developed for the synthesis of the title compounds (III) and (VI) via acid-catalyzed imine formation, intramolecular cyclization and dehydrogenation. -(WU*, C.-P.; DEVULAPALLY, R.; LI, T.-C.; KU, C.-K.; CHUNG, H.-C.; Tetrahedron Lett. 51 (2010) 37, 4819-4822, http://dx.
