The combination of a three-component, solvent-free pyrrole synthesis performed under mechanochemical conditions with a TMSOTf-catalyzed oxonium-mediated cyclization gave general access to pyrrolo[2,1-a]isoquinoline derivatives under very mild conditions.

In this work, we accomplished the first total synthesis of chiral alkaloid pimprinol A and the facile construction of its natural congeners: pimprinine, pimprinethine, pimprinaphine, WS-30581A, WS-30581B, laboradorin 1, uguenenazole, balsoxine, texamine in one-pot from commercially available starting materials including amino acids. Further investigating into the mechanism revealed that this improved transformation was achieved by the integration of iodination, Kornblum oxidation, condensation, decarboxylation, annulation, and oxidation reaction sequence.
Logic design and synthesis of quinoxalines via the integration of iodination/oxidation/cyclization sequences from ketones and 1,2-diamines

A novel protocol for the synthesis of quinoxalines has been developed from simple ketones and 1,2-diamines. This process underwent a logic approach to bis-substituted quinoxalines via a consecutive iodination/Kornblum oxidation/cyclization in the presence of I2/CuO/DMSO and to mono-substituted quinoxalines via an iodination/cyclization/aromatization in the presence of I2/CuO/K3PO4·3H 2O.
Direct α-iodination of aryl alkyl ketones by elemental iodine activated by 1-chloromethyl-4-fluoro-1,4-diazoniabicyclo[2.2.2]octane bis(tetrafluoroborate)
Jereb, Marjan,Stavber, Stojan,Zupan, Marko
, p. 853 - 858 (2007/10/03)
Selective introduction of an iodine atom at the α-carbonyl position in various aryl alkyl ketones was effectively achieved by reaction of target molecules with elemental iodine in the presence of N-F reagents. The best results were obtained by using 1-chl
