We have developed a simple method for the chemoselective aromatization of tetrahydro‐ β ‐carboline with selective nondeallylation O ‐allyl groups in the presence of iodine (100 mol %) in dimethyl sulfoxide/H 2 O 2 . A convergent approach toward the oxidative aromatization with selective deallylation (deprotection) of O ‐allyl‐tetrahydro‐ β ‐carboline using iodine in dimethyl sulfoxide/HCl has been described. The present protocol contains cheap catalyst, easy work up, normal reaction conditions, and high selectivity.
