Palladium catalysed tandem cyclisation–anion capture processes. Part 8 : In situ and preformed organostannanes. Carbamyl chlorides and other starter species
摘要:
A sequential one-pot process is reported involving in situ, palladium catalysed, formation of a series of tributylstannyl-1,2-carbo and heterocyclic dialkylidene-5-membered rings from the corresponding 1,6-diynes and Bu3SnH. These substrates and other organostannanes are then combined with carbamyl chlorides and iodobenzenes containing proximate alkene and alkynyl groups in palladium catalysed cyclisation-anion capture cascades affording a diverse range of heterocycles in good yield.

reaction of two aryl metal reagents is described. An equivalent amount of two arylGrignard or lithium reagents, after mediation by an equivalent amount of simple ClTi(OEt)3, was facilely assembled under the catalysis of 1 mol % of CoCl2/10 mol % of DMPU using oxygen. The cross-couplings between various aryl metal reagents, especially between two structurally similar arylGrignardreagents, proceeded smoothly

The present invention provides a novel (1,3-butadien-2-yl)methylamine derivative and a preparation method thereof. The (1,3-butadien-2-yl)methylamine derivative having the 1,3-diene substituent at the alpha-position is an useful precursor in preparing various amine compounds having biochemical activities.

Two efficient palladium-catalyzed intramolecular alpha-arylation reactions of alpha-amino acid esters have been developed that allow either 1-isoindolecarboxylic acid esters or the corresponding isoindolines to be selectively synthesized simply by a slight change of reaction conditions.
