substituents are formed stereospecifically by Prins−pinacol cyclizations of unsaturated α-dithianyl acetals 14a−e or 15a−e. These results show that the topography (boat or chair) of the Prins cyclization of the sulfur-stabilized oxocarbenium ions generated from acetals 14a−e or 15a−e is controlled by the stereoelectronic influence of the allylic substituents, with steric effects playing a minor role.
