A New Route for the Synthesis of 3-Methoxythiophenes
摘要:
A new synthesis of 4-substituted, 5-substituted and 4,5-disubstituted 3-methoxythiophenes is reported. The reaction takes place in three steps in nealy quantitative yields starting from methyl 3-hydroxythiophene-2-carboxylates.

A general method for the Pd-catalyzed coupling of methanol with (hetero)aryl halides is described. The reactions proceed under mildconditions with a wide range of aryl and heteroaryl halides to give methyl aryl ethers in high yield.

A series of dimethyl phthalates have been prepared from methoxythiophenes and dimethyl acetylenedicarbocylate (DMAD) in xylene. When the reaction is carried out in acetic acid, thienylfumarates are obtained.
