Publikováno v: Advanced Synthesis & Catalysis. 350:2250-2260

A series of enantiopure ligands based on the aminoindanol scaffold, but differing in regio- and stereochemistry has been synthesized. These ligands have been conveniently derivatized and their catalytic efficiency in different enantioselective reacti
