A new and efficient synthesis of a naturally occurring amide alkaloid, N-isobutyl-4,5-epoxy-2(E)-decenamide isolated from the roots of Piper nigrum has been described involving a total of nine steps. Octanal and 2-bromoacetic acid have been used as the starting materials.

Several optically active Nb(salan) complexes were synthesized, and their oxidation catalysis was examined. A dimeric μ-oxo Nb(salan) complex that was prepared from Nb(OiPr)5 and a salan ligand was found to catalyze the asymmetric epoxidation of allylic alcohols using a urea-hydrogen peroxide adduct as an oxidant with good enantioselectivity. However, subsequent studies of the time course of this epoxidation and of the relationship between the ee of the ligand and the ee of the product indicated that the μ-oxo dimer dissociates into a monomeric species prior to epoxidation. Moreover, monomeric Nb(salan) complexes prepared in situ from Nb(OiPr)5 and salan ligands followed by water treatment were found to catalyze the epoxidation of allylic alcohols better using aqueous hydrogen peroxide in CHCl3/brine or toluene/brine solution with high enantioselectivity ranging from 83 to 95% ee, except for the reaction of cinnamyl alcohol that showed a moderate ee of 74%. This is the first example of the highly enantioselective epoxidation of allylic alcohols using aqueous hydrogen peroxide as an oxidant.

, p. 657 - 658 (2007/10/03)
Lewis acid-mediated addition of allylstannanes to ketones adjacent to the allyl system of π-allyltricarbonyliron lactone complexes generates the corresponding homoallylic tertiary alcohols with excellent diastereocontrol.
CYCLODEXTRIN-H2O2: A NEW SYSTEM FOR ASYMMETRIC EPOXIDATION
Hu, Ying,Harada, Akira,Takahashi, Shigetoshi
, p. 1607 - 1610 (2007/10/02)
Asymmetric epoxidation of trans-cinnamaldehyde and chalcone by the use of H2O2 as an oxidizing agent in alkaline media in the presence of cyclodextrins gave the corresponding epoxides with enantiomeric excess up to 8percent.
