A new strategy for the enantioselective construction of chiral 2,3-cis-dimethyldihydrobenzofurans has been developed by a ruthenium-catalyzed asymmetric hydrogenation of racemic α-aryloxybutanone via dynamic kinetic resolution (DKR), combined with a palladium-catalyzed intramolecular reductive Heck cyclization. Starting from optically active 2,3-cis-dimethyldihydrobenzofuran, the natural products (+)/(-)-PI-220 and (+)-3-epi-furaquinocin C were synthesized in high yields.

A series of new dihydrothienopsoralen derivatives were synthesized from 6-hydroxybenzo[b]furan in four steps in good yield. These compounds were prepared as potential photosensitizing and chemotherapeutic agents for psoriasis. The spectroscopy study in al
