Abstract: The treatment of a, b-unsaturated acetals 1-4 with Schlosser's reagent LICKOR produces alkoxy-dienes 5-11 that can be readily transformed into allyl chlorides 12-21 by reaction with NCS. The halides can be obtained with a protected or unprotected carbonyl function, depending on the reaction conditions. The chlorination reaction proceeds by the electrophilic attack on the conjugate system that, depending on the substrate, affords both ...
