Chiral cyclopentene derivatives, e.g. I, were prepared via asym. organocatalytic [3+2] cycloaddition between allenoates, e.g. CH2:C:CHCO2Et, and dual activated olefin, e.g. II, using bifunctional N-acylaminophosphine catalysts, e.g. III.(S)-1-(Diphenylphosphino)-3,3-dimethylbutan-2-amine(cas: 286454-86-2SDS of cas: 286454-86-2) was used in this study.
(S)-1-(Diphenylphosphino)-3,3-dimethylbutan-2-amine(cas:286454-86-2) is one of aminophosphine type ligands. An increased interest in aminophosphine type ligands used for asymmetric synthesis has been witnessed.SDS of cas: 286454-86-2 This growth in popularity of aminophosphine ligands in asymmetric synthesis is in part due to the growing number of convenient synthetic pathways leading to useful ligand sets.
