Abstract
The first example of controllable site-selective pathways to construct 4- and 5-hydroxyalkyl-substituted imidazoles through a three-component reaction of amidines, ynals, and water has been documented. Particularly, the high regioselectivity of the reaction was simply switched by changing the additives. In addition, further 18O-labeled experiments to probe a plausible mechanism and the gram-scale synthesis were studied.
