Various 1,7-dienes, prepared efficiently in five steps from salicylaldehyde, react with diethyl thiophosphite (in the presence of AIBN) to form substituted chromans, which are potential precursors to cannabinoids. The influence of the substitution of the 1,7-diene on the efficiency of the radical cyclisation is discussed.
