Abstract The development of catalytic PIII/PV=O redox processes has transformed the Wittig reaction, traditionally plagued by stoichiometric phosphine oxide byproducts, into an efficient and more benign method for synthesizing alkenes. Recently, feasibility enantioselective catalysis was demonstrated using chiral catalysts, such as HypPhos. For example, atroposelective reaction Boc-MBH adducts, where endogenous base release facilitates ylide formation acid co-catalysis, allows enantiocontrol effective cycling, while catalyst-stereocontrolled reactions generally extend scope sustainability synthesis complex molecules. 1 Introduction 2 meso-Desymmetrizations 3 Atroposelective Catalysis 4 Conclusion
