Abstract

AbstractThe synthesis of new chiral TADDOL‐derived phosphate ligands is described. The ligands were efficiently synthesized on a multi‐gram scale in three steps starting from the readily available corresponding TADDOL and were fully characterized. An X‐ray structure was obtained and compared to known BINOL‐phosphates. Their use in the asymmetric Simmons–Smith cyclopropanation of both functionalized and unfunctionalized olefins gave the desired cyclopropanes in good yields and good to moderate enantioselectivities.
