摘要

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 conditions and consequent improvements were obtained from the use of dicarbonylrhodium iodide [Rh (CO) 2 I] 2 as catalyst precursor. The generalisation ...
