Relevant academic research and scientific papers

Stereoselective synthesis of (E)-chloroenynes or (E,E)-chlorodienes starting from a stereoisomeric mixture of 1,2-dichloroethylenes

Under palladium or nickel catalysis, a stereomeric mixture 1:1 of (Z) and (E)-1,2-dichloroethylene readily reacts with 1-alkynes, vinyl alanes or vinyl boranes to afford selectively the corresponding (E)-coupling product in good to excellent isolated yiel

Julia-Colonna asymmetric epoxidation reactions under non-aqueous conditions: Rapid, highly regio- and stereo-selective transformations using a cheap, recyclable catalyst

The asymmetric oxidation of some enones (Table 1), selected dienones 3-5, and a trienone 13 is accomplished using poly-L-leucine or poly-D-leucine and urea hydrogen peroxide under non-aqueous conditions. One of the resultant epoxy ketones 6 has been converted into the δ-lactones 19 and 22.
