Janssen-Mueller, Daniel published the artcileAnnulation of o-Quinodimethanes through N-Heterocyclic Carbene Catalysis for the Synthesis of 1-Isochromanones, Safety of 2-(Chloromethyl)benzonitrile, the publication is Organic Letters (2016), 18(17), 4444-4447, database is CAplus and MEDLINE.
The activation of 2-(bromomethyl)benzaldehydes using N-heterocyclic carbenes represents a novel approach to the generation of o-quinodimethane (o-QDM) intermediates. Coupling with ketones such as phenylglyoxylates, isatins, or trifluoromethyl ketones via [4 + 2] annulation gives access to functionalized 1-isochromanones.
