Synthetic strategy to access new multitarget neuroprotectors by conjugation of pharma-cophoric indole and bis(dimethylamino)phenothiazine moieties via 1-oxopropylene spacer was developed. The transformation was achieved by the cesium fluoride-catalyzed reaction of cycloalkaneindoles with 1-propenone. Effect of the synthesized compounds on neuronal NMDA receptors was evaluated by radioligand binding assay.

A convenient route has been developed for mono and dioxygenated carbazole alkaloids from 1-oxotetrahydrocarbazoles. The key step of the synthetic route is the aromatic process of 1-oxotetrahydrocarbazoles using molecular iodine. To our knowledge, this is the first report to manifest a direct synthesis of clausine E, mukonine, mukoeic acid and mukoline, from readily available ester-containing building
Iodine-catalyzed aromatization of tetrahydrocarbazoles and its utility in the synthesis of glycozoline and murrayafoline A: a combined experimental and computational investigation
A new protocol for the aromatization of tetrahydrocarbazoles has been achieved using a catalytic amount of iodine. The role of iodine has been explained by DFT, and its scope is extended to the total synthesis of glycozoline and murrayafoline A.

The development of multi-target-directed ligands (MTDLs) would provide effective therapy of neurodegenerativediseases (ND) with complex and nonclear pathogenesis. A promising method to create such potential drugs is combining neuroactive pharmacophoric groups acting on different biotargets involved in the pathogenesis of ND. We developed a synthetic algorithm for the conjugation of indole derivatives
