Abstract
A well-known characteristic of medium-sized rings (8-11-membered) is their ability to undergo facile transannular reactions. 2 Evidence has been found that transannular interactions involving sulfide sulfur may already take place in seven-membered rings. 3 We have recently described1 a facile reaction which occurs, in high yield, in the presence of trimethylsilyl iodide, on δ and ϵ hydroxy or alkoxy sulfides by intramolecular displacement ...
