概要
- 論文の詳細を見る
Regioselective introduction of various electrophiles (aldehydes, ketones, and imines) into piperidine skeleton at the 4-position was achieved with a catalytic amount of Pd(OAc)2/PPh3 in the presence of excess Et2Zn. In addition, enantioselective introduction of benzaldehyde into piperidine derivatives was accomplished by using chiral phosphine ligand with moderate enantioselectivity.
