Palladium-Catalyzed Synthesis of α‑Diimines from Triarylbismuthines and Isocyanides

, 2016
In this study, we report a highly selective coupling reaction between triarylbismuthines and isocyanides using palladium diacetate as the catalyst, affording α-diimines, with the formation of three C–C bonds. Among several aryl sources (Ar–YLn: Y = B, Sn,

Pyrrolidinone and Piperidinone Isocyanides from Isocyano Esters

, 2014
International audienceThe alkylation of isocyano esters with 1,2- and 1,3-dibromoalkanes affords bromo isocyanides. Under treatment with various amines the latter form new isocyano-substituted lactams, which can be further used in Passerini or Ugi ...

Synthesis of 2,4-Diiodoquinolines via the Photochemical Cyclization of o-Alkynylaryl Isocyanides with Iodine

, 2016
Upon photoirradiation of o-alkynylaryl isocyanides in the presence of iodine, the intramolecular cyclization of o-alkynylaryl isocyanides proceeds to afford the corresponding 2,4-diiodoquinolines in good yields.

Passerini Reactions on Biocatalytically Derived Chiral Azetidines

Molecules, 2016
The purpose of this study was to explore a series of Passerini reactions on a biocatalytically derived enantiopure azetidine-2-carboxyaldehyde in order to obtain, in a diastereoselective manner, polyfunctionalised derivatives having the potential to be ...

Palladium-Catalyzed Multicomponent Reaction (MCR) of Propargylic Carbonates with Isocyanides

, 2016
A palladium-catalyzed multicomponent reaction (MCR) of propargylic carbonates with isocyanides is reported. Remarkably, the orderly insertion of isocyanides affords two types of valuable N-heterocyclic products (Z)-6-imino-4,6-dihydro-1H-furo­[3,4-b ...

Palladium-Catalyzed Synthesis of 2‑Aminobenzoxazinones by Aerobic Oxidative Coupling of Anthranilic Acids and Isocyanides

, 2016
Isocyanides have emerged as valuable C1 building blocks in palladium catalysis. Their potential has, however, mainly been exploited for the synthesis of amidines and amidine-containing heterocycles. To illustrate the broader applicability of isocyanides,
