## Abstract The rhodium‐catalysed carbonylative addition of arylboronic acids to propargylic alcohols yields gamma‐hydroxy enones that are readily cyclised through a dehydration step to the corresponding furan analogues. The transformation was improved thanks to the screening of the reaction condit
