Effects of Substituents on the Chlorination of Methyl 3-Hydroxythiophene-2-carboxylate and on the Reaction of the Resulting Chlorinated Products with Active Hydrogen Containing Compounds

The title tandem reactions that produce 5-substituted compounds of methyl 3-hydroxythiophene-2-carboxylate can also be applied with a minor modification to the 4-alkyl and 4-aryl derivatives thereof.On the other hand, 5-alkyl and 5-aryl derivatives that undergo a similar smooth chlorination behave in the second reaction in a different manner.
