Figure Presented. A highly diastereoselective binary hydroamination of a 5-amino-1,8-diene containing a 2-(5-ethyl-2-thienyl)ethenyl terminator has been utilized in an efficient synthesis of (±)-xenovenine (1). A pronounced rate enhancement was observed for cyclization onto the 2-(heteroaromatic)ethenyl group in comparison to a simple 1,2-disubstituted alkene.

The hydroallylation of allenes was developed by employing a hydrosilane and allyl chlorides in the presence of a copper catalyst. The reaction provided (E)-1,5-dienes mainly in good to high yields.

The Barbier-type allylation of isatin imines with allylic chlorides was achieved by using metallic barium as the promoter. Various α-allylated 3-amino-2-oxindoles were synthesized from the corresponding allylic chlorides and isatin imines. The double-bond geometry of allylic chlorides was retained throughout the reaction. An arylic bromide or iodide functionality of the products was robust to metalation under the optimum reaction conditions.

Click! Formal [3+2] cycloadditions of 2-nitrosopyridine with various allylstannanes give 4-stannyl-substituted isoxazolidines. The use of [Cu(MeCN)4]PF6, in combination with a Walphos ligand, leads to excellent enantioselectivies and high yields. With cis-2- alkenylstannanes as nucleophiles, 3-alkyl-4-stannyl-substituted isoxazolidines are formed with excellent diastereo- and enantioselectivities. Copyright
Alkenyl-copper derivatives. 28 (1) : Stereospecific synthesis of tertiary allylic amines of E and Z configuration
Germon, C.,Alexakis, A.,Normant, J. F.
, p. 377 - 389 (2007/10/02)
Aminoethers and aminothioethers react smoothly with organocopper and cuprate reagents to afford tertiary amines.The use of Z alkenyl cuprates or E alkenyl aluminium derivatives leads to Z or E tertiary allylic amines.Polysubstituted and variously functionalized alkenyl copper reagents react in the same way, and a straightforward synthesis of pure N,N-diethylnerylamine is described.The stereoisomeric purity of these allylic amines is in the 99.5-99.9percent range, and their conversion to the corresponding allylic chlorides is not accompanied by any stereochemical scrambling.
