One variation of this reaction uses phenyllithium to convert an erythro intermediate to a threo one, and the same product can be obtained via the alternative Julia reaction.
One variation of this reaction uses phenyllithium to convert an erythro intermediate to a threo one, and the same product can be obtained via the alternative Julia reaction. Stabilized reagents are used in the HWE reaction, which is a modification of it, and the aforementioned Schlosser modification allows for the synthesis of the Z-product rather than the E-one. Its final step sees the decomposition of a four-member ring into the product and triphenylphosphine oxide, and the first step is the preparation of a zwitterionic compound from a haloalkane. FTP, name this reaction that creates an alkene from a ketone using a phosphonium ylide.
