Abstract
A simple and highly stereoselective method has been developed for the synthesis of (Z)-β-iodo Baylis-Hillman adducts using CeCl3·7H2O/NaI as an inexpensive and readily available reagent system. High conversions and enhanced Z-selectivity together with the environmentally benign nature of the CeCl3·7H2O/NaI reagent system makes this method an attractive alternative to established methods.
