Description	The use of microwave irradiation was found to significantly accelerate a one-pot reaction sequence involving a base-catalyzed 5-exo cyclization of appropriately substituted 4-alkyn-1-ols and subsequent Claisen rearrangement of the intermediate 2-methylene tetrahydrofuran derivatives. In most cases, the resulting cycloheptanoid ring systems were produced in a matter of minutes when subjected to microwave irradiation. The use of solvent-free conditions was also found to be compatible with the reaction sequence.
