Process for producing cycloalkyl [b]benzofurans

The present invention provides a process for producing an optically active compound of cycloalkyl[b]benzofuran using a readily available optically active compound as a starting material by a reaction using a transition metal or the Mitsunobu reaction, or

Synthesis of optically active cyclopenta[b]benzofuran as a precursor of m-phenyleneprostacyclin

The optically pure cyclopenta[b]benzofuran derivatives (-)-1 and (-)-2 were synthesized from (+)-(1S,4R)-cis-4-acetoxy-2-cyclopenten-1-ol [(+)-3] via sequential Mitsunobu reaction and palladium-catalyzed allylic substitution with phenol derivatives followed by SN2′ intramolecular cyclization.
