  摘要：

  A range of tertiary N-allylamines derived from 1,2,3,4-tetrahydroisoquinoline undergo oxidative cyclisation, induced by Ag2CO3, to pyrrolo-dihydroisoquinolines in moderate to good yield. Analogous oxidative cyclisations are reported for N-allyl-tetrahydro-beta-carbolines and a pyrrolidine. The reactions proceed via formation of a 1,5-dipole followed by an electrocyclisation and subsequent aromatisation.

• Achieving Control over the Branched/Linear Selectivity in Palladium-Catalyzed Allylic Amination
  作者：Igor Dubovyk、Iain D. G. Watson、Andrei K. Yudin

  DOI：10.1021/jo3025253

  日期：2013.2.15

  Palladium-catalyzed reaction of unsymmetrical allylic electrophiles with amines gives rise to regioisomeric allylic amines. We have found that linear products result from the thermodynamically controlled isomerization of the initially formed branched products. The isomerization is promoted by protic acid and active palladium catalyst. The use of base shuts down the isomerization pathway and allows for the preparation and isolation of branched allylic amines. Solvent plays a key role in achieving high kinetic regioselectivity and in controlling the rate of isomerization. The isomerization can be combined with ring-closing metathesis to afford the synthesis of exocyclic allylic amines from their endocyclic precursors.
• Chasing the Proton Culprit from Palladium-Catalyzed Allylic Amination

  We have found that the addition of base has a significant effect on palladium-catalyzed allylic amination. The long-standing problem of controlling the branched-to-linear ratio has been solved. In the presence of DBU and inexpensive, readily available ligands, palladium-catalyzed allylation proceeds under kinetic control, leading to high branched selectivity. Given the widespread utility of palladium-catalyzed allylic amination, we expect that these findings will be relevant in many areas ranging from asymmetric catalysis to target-oriented synthesis.
