Stereoselective crossed aldol reaction via boron enolate generated from alpha-iodoketones and 9-BBN-H
Boron enolates were in situ generated smoothly by treating alpha-iodo ketones with 9-BBN-H, and aldols were produced in highly diastereoselective manner by successive reaction with various aldehydes at low temperature.
