ABSTRACT

The iododecarboxylation reaction of α-carboxylate, α-cinnamoyl ketene cyclic dithioacetals 2 was successfully performed with iodine as halogenation reagent and in water insensitive media. This reaction provides a mild and efficient method for the preparation of α-iodo, α-cinnamoyl ketene cyclic dithioacetals 3 which are important kinds of potential new intermediates to be valued.
