Thiopyranobenzofuran 9 possessing benzofuran and methylenethiopyran structures in the molecule was synthesized starting from 1-chloro-4-methoxy-2-nitrobenzene 11.Some reactions (formylation, protonation and catalytic hydrogenation) on 9 were examined.The 2-position of 9 was highly reactive toward electrophilic reagents and the furan ring was readily reduced by catalytic hydrogenation with palladium-charcoal.Thiopyranobenzofuran 9 has both properties of methylenethiopyran and benzofuran.
