Abstract
Herein, we report the first nickel-catalyzed tandem dimerization/hydroheteroarylation
of isoprenes with indoles, using a catalytic system consisting of
a heteroleptic Ni(II) complex Ni(IPr*OMe)[P(OEt)3]Br2 and a base NaOtBu. This
system provides easy access to a range of C2-substituted cyclic monoterpenoid
indoles with high regioselectivity under solvent-free conditions.
This tandem transformation shows good compatibility with indoles bearing
various functional groups, such as esters, acetals, silanes, and boronate
esters. The tandem transformation is also applicable to other heteroarenes,
including pyrroles, (benzo)thiophenes, (benzo)furans, benzimidazoles,
pyrazoles, quinazolones, imidazo[1,2-a]pyridines,
and pyridines.
期刊介绍:
Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
