摘要:Abstract(#br)High enantioselectivities have been obtained for asymmetric epoxidation of olefins using a fructose-derived chiral ketone as catalyst and hydrogen peroxide as primary oxidant.

摘要:Abstract(#br)N -Aryl-substituted oxazolidinone-containing ketone catalysts for the asymmetric epoxidation of olefins can be efficiently prepared from d -glucose and anilines.

摘要:A Pd‐catalyzed regioselective hydroesterification of olefins with 2,2,2‐trifluoroethyl formate (TFEF) is described. Either linear or branched esters can be selectively obtained with proper ligands in most cases. The reaction process is operationally simple and involves no to...

摘要:Abstract(#br)Asymmetric epoxidation of substituted cis -β-methylstyrenes using N -aryl substituted oxazolidinone-containing ketones as catalysts shows that substituents on the phenyl group of the olefin have significant positive effects on the enantioselectivity of the epoxi...
