A new synthetic method to obtain the potential anticancer agent 5,6,11,12,17,18,23,24-octahydrocyclododeca[1,2-6:4,5-b':7,8-b '':10,11-b''']tetraindole ((let), starting from 1H-indole-3-carboxaldehyde and sulfamide, is described. Although a mixture of CTet and cyclic indole trimer (CTr) is formed, higher CTet/CTr ratio (4:6) and Cret yield (15%) make our protocol more favorable than those reported in the literature. A discussion on the possible reaction mechanism is reported. (C) 2011 Elsevier Ltd. All rights reserved,
