Vinyl sulfones (E)-4-tosyl-3-buten-1-ol (2) and its MOM-derivative 6, prepared by iodosulfonylation-dehydroiodination of 3-buten-1-ol (1), are regio and stereoselectively lithiated at the 4-position to afford intermediates 3 and 7, respectively. The protected derivative 7 can be alkylated and acylated at the vinylic position and both intermediates can also react with carbonyl compounds to give 1,5-diols
