The power of palladium: The total synthesis of the alkaloid hodgkinsine B has been achieved with just six isolated intermediates and only four chromatographic operations. The route involves a palladium-catalyzed enantioselective desymmetrizing N-ally

A sequential CH functionalization strategy for the synthesis of the marine alkaloid dictyodendrin B is reported. Our synthesis begins from commercially available 4-bromoindole and involves six direct functionalizations around the heteroarene core

Isoxazolidines and tetrahydro-1,2-oxazines were produced by a tandem deprotection-intramolecular Michael addition of hydroxylamines. For tetrahydrooxazine formation, high stereoselectivity was observed, even when a quaternary centre was formed.

o-Halo benzoates can be combined with monoalkyl ureas in a tandem palladium-catalyzed arylation-ester amidation sequence to deliver quinazolinedione products. The reactions are regioselective for formation of the 3-N-alkyl isomers. Significant variat
