The Cope rearrangement permits the ring expansion or contraction of cycloalkanes containing a suitable 1,5-diene system. Thus ci.s-1,2-divinylcyclopropanes and cyclo-butanes readily form cycloheptadienes2 and cyclooctadienes 3 respectively. Conversely 4

## Abstract 2‐(1‐Hydroxyalkyl)azetidines react with bis(trichloromethyl) carbonate (BTC) after basic treatment to afford 4‐(2‐chloroethyl)oxazolidinones. The scope of this rearrangement was examined in detail and its efficiency was shown to depend on the class of the reacting alcohol and on the sub
