Sebastian Julia developed a version of this reaction starting from chalcone derivatives and making use of a poly-L-leucine for enantioselectivity, while another stereospecific reaction of this type uses a fructose derived catalyst.  
Sebastian Julia developed a version of this reaction starting from chalcone derivatives and making use of a poly-L-leucine for enantioselectivity, while another stereospecific reaction of this type uses a fructose derived catalyst.  One example of this class of reactions makes use of a poorly understood titanium tartrate dimer catalyst, while a similar reaction that doesn't require a directing functional group makes use of a salen-type ligand bonded to a manganese ion.  In that reaction, a pi bond approaches the activated transition metal complex in a top-on approach.  Another version of this reaction may be performed on a alkene via a peracid such as mCPBA through a butterfly mechanism; that version is named for Prilezhaev. Yet another reaction of this type is, much like a reaction that produces diols, named after Sharpless. FTP, name these types of reaction that forms  certain three membered ether ring.
