Abstract

A Pd-catalyzed atroposelective C-H allylation with 1,1-disubstituted alkenes was developed for the synthesis of enantioenriched N-aryl peptoid atropisomers via β-H elimination using commercially available and inexpensive L-pGlu-OH as a chiral ligand. Exclusive allylic selectivity was achieved. Additionally, a series of enantioenriched N-aryl peptoid atropisomers were obtained in synthetically useful yields with excellent enantioselectivities (up to 90% yield and 97% ee).
