Nickel-catalyzed Mizoroki-Heck- versus Michael-type addition of organoboronic acids to alpha,beta-unsaturated alkenes through fine-tuning of ligands.
Lin PS, Jeganmohan M, Cheng CH. Lin PS, et al. Chem Asian J. 2007 Nov 5;2(11):1409-16. doi: 10.1002/asia.200700128. Chem Asian J. 2007. PMID: 17849401
By tuning the ligands of the nickel complexes and the reaction conditions, Michael-type addition was achieved in a very selective manner. Thus, various p- and o-substituted arylboronic acids or alkenylboronic acid reacted smoothly with activated alkenes in CH3CN at …

Common Strategy for the Synthesis of Some Strychnos Indole Alkaloids.
Maertens G, Deruer E, Denis M, Canesi S. Maertens G, et al. J Org Chem. 2020 May 1;85(9):6098-6108. doi: 10.1021/acs.joc.0c00572. Epub 2020 Apr 10. J Org Chem. 2020. PMID: 32227835
Although these compounds have different connections, substituents, and functionalities, their main core can be produced via the formation of a common functionalized tetracyclic subunit, which is rapidly obtained by an oxidative de-aromatization process mediated by a hypervalent i …
