## Abstract Four alicyclic furan compounds have been synthesized with incorporation of ^18^O in the furan oxygen. Basically, a stable ketonic intermediate of the synthetic scheme was exchanged with H~2~^18^O in THF with a catalytic amount of HCl.

Abstract
A facile synthesis for the efficient incorporation of ^14^C or ^13^C into trisubstituted furan compounds has been elaborated. 3βMethylβ4,5,6,7βtetrahydrobenzofuran was prepared in five steps from methylβ and ethylβ2βoxoβ1 cyclohexanecarboxylate with overall yield of 65%. Radioactive label was nearly quantitatively incorporated. One new compound, 7, has been prepared in elaborating the synthetic sequence.
