  Palladium-catalyzed regio- and stereoselective allylamination of allenic alcohols

  摘要：

  Palladium [PdCl2(PhCN)2 or Pd2(dba)3.CHCl3] catalyzes the reaction of O-(2,3-butadienyl) N-tosylcarbamates 1 with allylic chlorides to selectively provide trans-4,5-disubstituted oxazolidin-2-ones 2 in good yields. Under similar conditions, Pd(PPh3)4 catalyzes an N-allylation of 1 to give 3, and chloro-pi-allylpalladium(II) dimer promotes a dimerization of 1g and gives 4 as a major product together with 2.

• Palladium(II)-Catalyzed Tandem Reaction of Intramolecular Aminopalladation of Allenyl <i>N</i>-Tosylcarbamates and Conjugate Addition

  日期：2001.11.1

  A divalent palladium-catalyzed tandem cyclization-coupling reaction of allenyl N-tosylcarbamates and acrolein was developed. The reaction gave aldehyde-functionalized 2-oxazolidinones in one step with high regioselectivity. A mechanism involving intramolecular aminopalladation of allene, followed by insertion of alkene and C-Pd bond protonolysis, is proposed. [reaction: see text]

  Palladium [PdCl2(PhCN)(2) or Pd-2(dba)(3) . CHCl3 (dba = dibenzylideneacetone)], in the presence of a base (Et(3)N or K2CO3) in THF at room temperature, catalyzes an allylaminocyclization of 2,3-butadienyl tosylcarbamates 1 with allylic chlorides to selectively provide trans-4,5-disubstituted 2-oxazolidinones 2 in good yields. Under similar conditions, Pd(PPh(3))(4) catalyzes an N-allylation of 1 to give 3. A limited number of 3,4-pentadienyl tosylcarbamates 5 undergo the allylaminocyclization to provide tetrahydro-1,3-oxazin-2-ones 6. In the absence of an allylic chloride, Pd(PPh(3))(4) and PdCl2(PhCN)(2) catalyze a formal dimerization of 1 to provide C-4-triene-substituted 2-oxazolidinones 4 in moderate to good yields.
