## Abstract The BF~3~ · Et~2~O‐ and the CH~3~SO~3~H‐catalysed rearrangements of 10 α‐vinylcyclobutanones have been examined. With little acid, the β,β‐dialkyl derivatives **1** were transformed into linear dienones **2** and **3**; with more acid, they were converted into cyclopentenones **4** by _

Ihe boron triflucride catalysed rearrangements of steroidal epcxides have been widely reported (1). Recently, considerable interest has been shown in the backbone rearrangement of 4,5-and 5,6-epoxy-steroids (1). In an attempt to elucidate the mechanism of these rearrangements in more detail, we have
