Straightforward access to 4-membered sulfurated heterocycles: Introducing a strategy for the single and double functionalization of thietane 1-oxide

A strategy for the stereoselective functionalization of thietane 1-oxide has been developed. Mono (C2 substituted) and doubly (C2, C4 disubstituted) functionalized thietanes have been obtained from the readily available thietane 1-oxide by using the corresponding organometallic intermediates that reacted with electrophiles leaving intact the 4-membered ring.
