摘要：

An efficient one-pot, three-component coupling reaction for the synthesis of beta-iodo-alpha-(hydroxyalkyl)acrylates has been developed. As the iodine source as well as the Lewis acid mediator, diethyl aluminium iodide undergoes a Michael-type addition with methyl propynoate to form an active beta-iodo allenolate intermediate, which in turn attacks various aldehydes or ketones to afford beta-iodo Baylis-Hillman adducts in excellent yields with high Z-selectivity.
