摘要/描述

An indium complex of chiral PYBOX was applied in the catalytic asymmetric allylation of ketones in the ionic liquid. It was found that this chiral indium complex was strong enough to promote the reaction of ketones with allyltributylstannane smoothly. The products were obtained in moderate to high enantioselectivities, and the chiral catalyst immobilized in the ionic liquid could be reused with comparable enantioselectivities and yields.
