Abstract:The dithioacetalization of lactaldehyde derivatives with ethane-1,2-, propane-1,3-; butane-1,4- and pentane-1,5-dithiols in the presence of 4 mol% of scandium triflate has been described. A series of cyclic dithioacetals were obtained with yields ranging from quantitative to 37%. The dithioacetalization of lactaldehyde derivatives with butane-1,4-dithiol and pentane-1,5-dithiol groups are accompanied by the formation of 14- and 16-membered macrocyclic sulfur structures with yields of 3% and 18%, respectively. … Show more
