應用

(R,R,R)-SPIRAP is a chiral C2-symmetric spiroketal-containing ligand developed in the Nagorny lab for asymmetric catalysis. It can be used in variety of stereoselective transformations, including: Ir-catalyzed hydroarylation, Pd-catalyzed allylic alkylation, Pd-catalyzed Heck couplings, and Rh-catalyzed hydrogenation.

Product can be used with our benchtop hydrogen generator, H-Genie Lite (Z744083)

We present an expedient and economical route to a new spiroketal-based C2 -symmetric chiral scaffold, termed SPIROL. Based on this spirocyclic scaffold, several chiral ligands were generated. These ligands were successfully employed in an array of stereoselective transformations, including in

The Nagorny group has designed a new class of spiroketal-based chiral scaffolds termed SPIROLs. The SPIROL-based ligands have demonstrated excellent performance in a variety of Pd-, Rh- and Ir-catalyzed transformations while being easily accessible. Other focus areas are asymmetric catalysis, chiral catalyst, ligand design, which are all dedicated to the development of immobilized organic catalysts.
