Abstract

In this paper, we developed a new bisoxazoline ligand with a spiro skeleton and a α-naphthylmethyl substituent, i.e. (Ra,S,S)-L3, which has been successfully applied to the highly enantioselective cyclic allylation based on the carbopalladation of 3,4-allenyl hydrazines with ee values ranging from 92–95%.
